Question 308691: If x^2 + x – 6 = 0, then x is:
Answer by texttutoring(324)   (Show Source):
You can put this solution on YOUR website! x^2 + x – 6 = 0
This is a quadratic (there is an x^2 term), so you need to solve it by factoring. You will get two answers.
You need to find two numbers that multiply to -6 and also add up to +1.
Those numbers are 3 and -2.
x^2 + x – 6 = 0
(x+3)(x-2)=0
So, either (x+3)=0 or (x-2)=0.
If x+3=0, x=-3
If x-2=0, x=2
x=-3, x=2 are your answers.
