Question

What are the roots of the polynomial equation? x2+6x−72=0 Enter your answers in the boxes. x= or x=

Answer 1

I found 2 numbers, which had to add to give 6 and multiply to give - 72
To do this, I listed out the factors of 72 and got
-12 * 6 = - 72
-12 + 6 = 6

So I know the roots will be
X = - 12
X = 6

Answer 2

I think is... X= 6, -12
