| Answer» Standard Algebraic Identities:Identity I: (a + b)2 = a2 + 2ab + b2Identity III: a2 – b2= (a + b)(a – b)Identity IV: (x + a)(x + b) = x2 + (a + b) x + ab.Identity V: (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.Identity VI: (a + b)3 = a3 + b3 + 3ab (a + b)Identity VIII: a3 + b3 + c3 – 3abc = (a + b + c)(a2 + b2 + c2 – ab – bc – ca) | |
