Question

Solve x2 + 18 = –9x.

Answer 1

you first step would be to add 9x to both sides, giving you:
x^2+9x+18=0

Now you next step is to think of two numbers that multiply to be 18 and add to 9, that way you can factor this quadratic

Answer 2

x^2 + 9x + 18 = 0

(x + 6) (x + 3) = 0

x = -6
x = -3
