Best ResponseYou've already chosen the best response.2write it in factored form: however with complex roots, do the following x = 1 +2i x1 = +2i (x1)^2 = 4i^2 = 4 (x1)^2 +4 = 0 x^2 2x +5 = 0 > (x3)(x1/3)(x^2 2x +5) Now just multiply it out

Best ResponseYou've already chosen the best response.2also if you don't want to deal with fractions: x = 1/3 3x = 1 3x1 = 0 Replace (x1/3) with (3x1) since they both yield the same zero of x=1/3
