Best ResponseYou've already chosen the best response.0(a+b)^ 2 = a ^2 + 2ab + b^ 2 (a+b)(c+d) = ac + ad + bc + bd a^ 2  b^ 2 = (a+b)(ab) (Difference of squares) a ^3 (+) b ^3 = (a (+) b)(a^ 2(+) ab + b ^2) (Sum and Difference of Cubes) x^ 2 + (a+b)x + AB = (x + a)(x + b) if ax^ 2 + bx + c = 0 then x = ( b (+)sqrt(b^ 2  4ac) ) / 2a (Quadratic Formula)
