I need to find the root and check my answer. X^2 + 5X - 14 = 0
I think the answer is X = 7 and x = - 2

You are so close! I'm assuming you factored the equation to get (x-2)(x+7).
Now set each of those equations to 0 to solve.
The answers to x-2=0 and x+7=0 are the roots.

So it should be broken down as X - 2 = 0
+2 +2
_____________
X = 2
Because the -2 and the +2 cancel out each other. So the answers should be
X = 2 and X = -7
Yes! Bingo!
