Question

Complete the equivalent equation for –7x – 60 = x2 + 10x.

(x +
)(x +
) = 0

What are the solutions of –7x – 60 = x2 + 10x?

x =

Answer 1

Start by moving all terms to one side:

0 = x^2 + 10x + 7x + 60 = x^2 + 17x + 60

Factor:

(x + 12)(x + 5) = 0

So the solutions are x = -12 or x = -5.
