What are two numbers that multiply to -8 AND add to 2 ?
OpenStudy (anonymous):
-2 and 4
OpenStudy (anonymous):
Ao now substtute it dat way... Its a quadratic u no...
Directrix (directrix):
w^2+2w-8 = w^2 + 4w - 2w -8 = w(w + 4) - 2(w + 4) = (w - 2) * (w + 4). That is factoring by grouping.
Directrix (directrix):
(w - 2) * (w + 4) = 0 So, w-2 = 0 or w + 4 = 0 Solve for w @higherlearning
