Answer:

x₁ = -17  x₂ = 8

Step-by-step explanation:

First we equal the equation to zero and simplify it

x² + 9x +44 - 180 = 0

x² + 9x - 136 = 0

Then, we look for to numbers that if we add them the result is +9 and if we multiply then the result is -136.

This numbers are 17 and -8

Then, we write the equation as a factors of two terms

(x+17) (x-8) = 0

and we equal if term to zero

x₁ + 17 = 0

x₁ = -17

x₂ -8 = 0

x₂ = 8
