## List of Algebra Formulas for Class 10

All the algebraic identities for class 10 formulas are provided here. A student may feel difficult to note them and read. To make it easy for them, all the important algebra formulas for class 10 are listed below.

Algebraic Identities For Class 10 |

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

\(\mathbf{(a-b)^{2}}\) \(=a^{2}-2ab+b^{2}\) |

\(\mathbf{\left (a + b \right ) \left (a – b \right ) }\) \( = a^{2} – b^{2}\) |

\(\mathbf{ \left (x + a \right )\left (x + b \right ) }\) \(= x^{2} + \left (a + b \right )x + ab\) |

\(\mathbf{\left (x + a \right )\left (x – b \right ) }\) \(= x^{2} + \left (a – b \right )x – ab\) |

\(\mathbf{\left (x – a \right )\left (x + b \right )}\) \(= x^{2} + \left (b – a \right )x – ab\) |

\(\mathbf{\left (x – a \right )\left (x – b \right ) }\) \(= x^{2} – \left (a + b \right )x + ab\) |

\(\mathbf{\left (a + b \right )^{3}}\) \( = a^{3} + b^{3} + 3ab\left (a + b \right )\) |

\(\mathbf{\left (a – b \right )^{3} }\) \(= a^{3} – b^{3} – 3ab\left (a – b \right )\) |

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

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

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

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

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

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

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

\(\mathbf{x^{3} + y^{3}}\) \(= (x + y) (x^{2} – xy + y^{2})\) |

\(\mathbf{x^{3} – y^{3}}\) \( = (x – y) (x^{2} + xy + y^{2})\) |

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

Linear Equation in Two Variables |

\(\mathbf{a_{1}x + b_{1}y + c_{1} }\) \(= 0\) |

\(\mathbf{a_{2}x+ b_{2}y + c_{2}} \) \(= 0 \) |
