What equation has solutions of -5 and 8?
x = -5 and x = 8 {set each solution equal to x}
x + 5 = 0 or x - 8 = 0 {added 5 and subtracted 8} (x + 5)(x - 8) = 0 {multiplied together and set equal to zero} x² - 3x - 40 = 0 {used FOIL method or distributive property} f(x) = x² - 3x - 40 {wrote as a function} Ask Algebra House
