Algebra Formulas

Algebra is a branch of mathematics that substitutes letters for numbers. An algebraic equation depicts a scale, what is done on one side of the scale with a number is also done to either side of the scale. The numbers are constants. Algebra also includes real numbers, complex numbers, matrices, vectors and much more. X, Y, A, B are the most commonly used letters that represent algebraic problems and equations.

Important Formulas in AlgebraHere is a list of Algebraic formulas –a2 – b2 = (a – b)(a + b)(a + b)2 = a2 + 2ab + b2a2 + b2 = (a + b)2 – 2ab(a – b)2 = a2 – 2ab + b2(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca(a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca(a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)(a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)
