Algebraic Identities For Class 9 |

(a+b)^{2}=a2^{2}+2ab+b2^{2} |

(a−b)^{ 2}=a^{2}−2ab+b^{2} |

(a+b)(a–b)=a^{2}–b^{2} |

(x+a)(x+b)=x^{2}+(a+b)x+ab |

(x+a)(x–b)=x^{2}+(a–b)x–ab |

(x–a)(x+b)=x^{2}+(b–a)x–ab |

(x–a)(x–b)=x^{2}–(a+b)x+ab |

(a+b)^{ 3}=a^{3}+b^{3}+3ab(a+b) |

(a–b)^{3}=a3^{3}–b^{3}–3ab(a–b) |

(x+y+z)^{ 2}=x^{2}+y^{2}+z^{2}+2xy+2yz+2xz |

(x+y–z)^{ 2}=x^{2}+y^{2}+z^{2}+2xy–2yz–2xz |

(x–y+z)^{ 2}=x^{2}+y^{2}+z^{2}–2xy–2yz+2xz |

(x–y–z)^{ 2}=x^{2}+y^{2}+z^{2}–2xy+2yz–2xz |

x^{3}+y^{3}+z^{3}–3xyz=(x+y+z)(x^{2}+y^{2}+z^{2}–xy–yz−xz) |

x^{2}+y^{2}=\(\frac {1}{2}\) [(x+y)^{ 2}+(x–y)^{ 2}] |

(x+a)(x+b)(x+c)=x^{3}+(a+b+c)x^{2}+(ab+bc+ca)x+abc |

x^{3}+y^{3}=(x+y)(x^{2}–xy+y^{2}) |

x3^{3}–y^{3}=(x–y)(x^{2}+xy+y^{2}) |

x^{2}+y^{2}+z^{2}−xy–yz–zx=\(\frac {1}{2}\) [(x−y)^{ 2}+(y−z)^{ 2}+(z−x)^{ 2}]< |
