Solve using any method

Factor the expression:

x

^{2}+x - 30 = (x+6)(x-5) = 0(because 6 and -5 are factors of

**-**30 that make 6x - 5x = x - second term)The product of two terms is zero if both are equal to zero or one of them.

It gives you x+6 = 0 and x-5 = 0 or

x = -6 and x = 5

Check the answer by substituting these numbers back into the expression. Both satisfy.
