Answer:

(m - 10) and (m - 2)

Step-by-step explanation:

Given

m² - 12m + 20

Consider the factors of the constant term (+ 20) which sum to give the coefficient of the m- term (- 12)

the factors are - 10 and - 2, since

- 10 × - 2 = + 20 and - 10 - 2 = - 12, thus

m² - 12m + 20 = (m - 10)(m - 2)
