**Quadratic Equation Formulas**

1. Quadratic Expression

A polynomial of degree two of the form ax^{2} + bx + c (a ≠ 0) is called a quadratic expression in x.

2. The Quadratic Equation

ax^{2} + bx + c = 0 (a ≠ 0) has two roots, given by

α = \(\frac{-b+\sqrt{b^{2}-4 a c}}{2 a}\) and β = \(\frac{-b-\sqrt{b^{2}-4 a c}}{2 a}\)

3. Nature of roots

The term b^{2} – 4ac is called discriminant of the equation. It is denoted by ∆ or D.

(A) Suppose a, b, c ∈ R and a ≠ 0 then

- If D > 0 ⇒ roots are real and unequal
- If D = 0 ⇒ roots are real and equal and each equal to -b/2a
- If D < 0 ⇒ roots are imaginary and unequal or complex conjugate.

(B) Suppose a, b, c ∈ Q, a ≠ 0 then

- If D > 0 & D is perfect square ⇒ roots are unequal & rational
- If D > 0 & D is not perfect square ⇒ roots are irrational & unequal

4. Conjugate roots

1. If D < 0 →

One root:

α + iβ

Other root:

α – iβ

then

2. D > 0 →

One root:

α + \(\sqrt{\beta}\)

Other root:

α – \(\sqrt{\beta}\)

5. Sum of roots

S = α + β = \(\frac{-b}{a}=-\frac{\text { Coefficient of } x}{\text { cofficient of } x^{2}}\)

6. Product of roots

P = αβ = \(\frac{c}{a}=\frac{\text { Constant term }}{\text { coefficient of } x^{2}}\)

7. Formation of an equation with given roots

x^{2} – Sx + P = 0

8. Relation between roots-and coefficients

If roots of quadratic equation ax^{2} + bx + c = 0 (a ≠ 0) are α and β then

- (α – β) = \(\sqrt{(\alpha+\beta)^{2}-4 \alpha \beta}\) = ± \(\frac{\sqrt{b^{2}-4 a c}}{a}=\frac{\pm \sqrt{D}}{a}\)
- α
^{2}+ β^{2}= (α + β)^{2}– 2αβ = \(\frac{b^{2}-2 a c}{a^{2}}\) - α
^{2}– β^{2}= (α + β)\(\sqrt{(\alpha+\beta)^{2}-4 \alpha \beta}\) = – \(\frac{b \sqrt{b^{2}-4 a c}}{a^{2}}=\frac{\pm \sqrt{D}}{a}\) - α
^{3}+ β^{3}= (α + β)^{3}– 3αβ(α + β) = – \(\frac{b\left(b^{2}-3 a c\right)}{a^{3}}\) - α
^{3}– β^{3}= (α – β)^{3}– 3αβ(α – β)\(\sqrt{(\alpha+\beta)^{2}-4 \alpha \beta}\) {(α + β)^{2}– αβ} = \(\frac{\left(b^{2}-a c\right) \sqrt{b^{2}-4 a c}}{a^{3}}\) - α
^{4}+ β^{4}= {(α + β)^{2}– 2αβ}^{2}– 2α^{2}β^{2}= \(\left(\frac{b^{2}-2 a c}{a^{2}}\right)^{2}-2 \frac{c^{2}}{a^{2}}\) - α
^{4}– β^{4}= (α^{2}– β^{2})(α^{2}+ β^{2}) \(=\frac{\pm b\left(b^{2}-2 a c\right) \sqrt{b^{2}-4 a c}}{a^{4}}\) - α
^{2}+ αβ + β^{2}= (α + β)^{2}– αβ - \(\frac{\alpha}{\beta}+\frac{\beta}{\alpha}=\frac{\alpha^{2}+\beta^{2}}{\alpha \beta}=\frac{(\alpha+\beta)^{2}-2 \alpha \beta}{\alpha \beta}\)
- α
^{2}β + β^{2}α = αβ(α + β) - \(\left(\frac{\alpha}{\beta}\right)^{2}+\left(\frac{\beta}{\alpha}\right)^{2}=\frac{\alpha^{4}+\beta^{4}}{\alpha^{2} \beta^{2}}=\frac{\left(\alpha^{2}+\beta^{2}\right)^{2}-2 \alpha^{2} \beta^{2}}{\alpha^{2} \beta^{2}}\)

(xii) nb^{2}= ac(1 + n)^{2}when one root is n times of another

9. Roots under particular cases

For the quadratic equation ax^{2} + bx + c = 0

- If b = 0 ⇒ roots are of equal magnitude but of opposite sign
- If c = 0 ⇒ one root is zero other is – b/a
- If b = c = 0 ⇒ both roots are zero
- If a = c ⇒ roots are reciprocal to each other
- If \(\left.\begin{array}{ll}

a>0 & c<0 \\

a<0 & c>0

\end{array}\right\}\) ⇒ both roots are of opposite signs - If \(\left.\begin{array}{l}

\mathrm{a}>0, \mathrm{b}>0, \mathrm{c}>0 \\

\mathrm{a}<0, \mathrm{b}<0, \mathrm{c}<0 \end{array}\right\}\) ⇒ both roots are negative - If \(\left.\begin{array}{l} \mathrm{a}>0, \mathrm{b}<0, \mathrm{c}>0 \\

\mathrm{a}<0, \mathrm{b}>0, \mathrm{c}<0

\end{array}\right\}\) ⇒ both roots are positive

10. Condition for common roots

Let quadratic equations are a_{1}x^{2} + b_{1}x + c_{1} = 0 and a_{2}x^{2} + b_{2}x + c_{2} = 0

(i) If only one root is common:

\(\frac{\alpha^{2}}{\mathrm{b}_{1} \mathrm{c}_{2}-\mathrm{b}_{2} \mathrm{c}_{1}}=\frac{\alpha}{\mathrm{a}_{2} \mathrm{c}_{1}-\mathrm{a}_{1} \mathrm{c}_{2}}=\frac{1}{\mathrm{a}_{1} \mathrm{b}_{2}-\mathrm{a}_{2} \mathrm{b}_{1}}\)

(ii) If both roots are common: \(\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}\)

11. Nature of the factors of the Quadrate Expression

- Real and different, if b
^{2}– 4ac > 0. - Rational and different, if b
^{2}– 4ac is a perfect square. - Real and equal, if b
^{2}– 4ac = 0.

12. Position for roots of a quadratic equation ax^{2} + bx + c = 0

(A) Condition for both the roots will be greater than k.

(i) D ≥ 0 (ii) k < –\(\frac{b}{2 a}\) (iii) af(k) > 0

(B) Condition for both the roots will be less than k

(i) D ≥ 0 (ii) k > –\(\frac{b}{2 a}\) (iii) af(k) > 0

(C) Condition for k lie between the roots

(i) D > 0 (ii) af(k) < 0

(D) Condition for exactly one root lie in the interval (k_{1}, k_{2}) where k_{1} < k_{2}

(i) f(k_{1}) f(k_{2}) < 0 (ii) D > 0

(E) When both roots lie in the interval (k_{1}, k_{2}) where k_{1} < k_{2}

(i) D > 0 (ii) f(k_{1}) . f(k_{2}) > 0

(F) Any algebraic expression f(x) = 0 in interval [a, b] if

(i) sign of f(a) and f(b) are of same then either no roots or even no. of roots exist.

(ii) sing of f(a) and f(b) are opposite then f(x) = 0 has at least one real root or odd no. of roots.

13. Maximum & Minimum value of Quadratic Expression

In a quadratic expression ax^{2} + bx + c

- If a > 0, quadratic expression has least value at x = –\(\frac{b}{2 a}\). This least value is given by \(\frac{4 a c-b^{2}}{4 a}=-\frac{D}{4 a}\)
- If a < 0, quadratic expression has greatest value at x = –\(\frac{b}{2 a}\). This

greatest value is given by \(\frac{4 a c-b^{2}}{4 a}=-\frac{D}{4 a}\)

14. Quadratic expression in two variables

The general form of a quadratic expression in two variables x & y is ax^{2} + 2hxy + by^{2} + 2gx + 2fy + c. The condition that this expression may be resolved into two linear rational factors is

∆ = \(\left|\begin{array}{lll}

a & h & g \\

h & b & f \\

g & f & c

\end{array}\right|\) = 0 ⇒ abc + 2 fgh – af^{2} – bg^{2} – ch^{2} = 0 and h^{2} – ab > 0

This expression is called discriminant of the above quadratic expression.
