Step-by-step explanation:
The quadratic expression cannot be factorized, because the discriminant is less than 0
<h3>How to factorize the expression?</h3>
The expression is given as:
x²+12x+180
Calculate the discriminant of the expresison using:
D = B² - 4AC
So, we have:
D = 12² - 4* 1 * 180
Evaluate
D = -576
Because the discriminant is less than 0, then the expression cannot be factorized
