ohh lol duh ok so you have to factor first. this factors into (5x+2)(x-1) then x is anything that makes those equal to 0 so x = -2/5 and 1

our goal is to fill in these: ( somethign here +/- somethign else here) ( somethign here +/- somethign else here) when both sets are multiples together you should get your original equation.

(5x+2)(x-1) because 5x times 1x = 5x^2 because 2 * -1 = -2 at the end of your equation and because 2*x = 2x and 5x * -1 = -5x and 2x -5x = -3x (your middle number)

Just for knowledge (5x+2)(x-1) set each to zero, and solve each for x 5x+2 = 0 5x = -2 x= -2/5 x-1 = 0 x = 1 answers for x = -2/5 and 1 ....but always plug them back in to be sure
