Important Algebraic Formulas (a+b)= a + b2 + 2ab (a - b)2 = a + b2 - 2ab a? – b2 = (a + b)(a-b) a? + b2 = (a + b)2 - 2ab a 2 or a? + b2 = (a - b)2 + 2ab = a3 + b3 = (a + b)(a? - ab + b) = (a + b)3 - 3ab(a+b) = = a? - b3 = (a - b)(a + ab + b) = (a - b)3 + 3ab(a - b) = - 2(a2 + b2) = (a + b)2 + (a - b)2 = (a+b)-(a - b)2 = 4ab = a++b+= (a + b)(a - b)[(a+b)2 - 2ab] ...
