Question 84670: Please solve the following inequalities and write the solutions in interval notation.
x^2-x-6>0 Answer by dolly(163) (Show Source):
You can put this solution on YOUR website! x^2 - x - 6 > 0
==> x^2 - 3x + 2x - 6 > 0
==> x(x-3) + 2(x-3) > 0
==> (x-3)(x+2) > 0
This is true only when x>3 or when x < -2
==> the solution is (-infinity, -2) U (3, infinity)
