|x^2+x|=12
Solve for x.
--------------
Tip: |a| = b when a = b or a = -b
In your case,
x^2 + x = 12 or x^2 + x = -12
I'll solve the first case for you:
x^2 + x = 12
x^2 + x - 12 = 0
(x + 4)(x - 3) = 0
x + 4 = 0 or x - 3 = 0
x = - 4 or x = 3
You will solve the second case same as above.
Hope it helps! John
