Question

Which statement best describes the equation (x + 5)2 + 4(x + 5) + 12 = 0?

Answer 1

After simplifying this equation, we get:

(2x+10)+(4x+20)+12=0

6x+42=0

6x=-42

x=-7.

We could describe this equation as a vertical line when graphed, or say that the solution to this equation is x=-7.

Hope this helps! :)
