Question

What are the factors of m2 – 12m + 20?

Answer 1

To make it simpler than the answer on top of this one the ANSWER IS B

Explanation:

Answer 2

m² - 12m + 20

m² ⇒ m * m
20 ⇒ - 10 * -2

(m - 10)(m - 2)
m(m - 2) - 10(m-2)
m² - 2m - 10m + 20
m² - 12m + 20

m - 10 = 0
m = 10

m - 2 = 0
m = 2
