Best ResponseYou've already chosen the best response.2if we are given roots as a and b , then the equation is given as (xa)(xb)=0 here the roots are 3+4i and 3 4i (x(3+4i))(x(34i)) x^2(3+4i+34i)x(916)=0 x^26x7=0

Best ResponseYou've already chosen the best response.0The simplest "Vieta's Formula" is x^2  (sum)x + (product) in this case we get x^2  6x + 25
