Consider the trinomial below. x2-9x+20 The factors of the given trinomial are () ().

Answer: (x - 4) (x - 5)

Step-by-step explanation:

Need two numbers whose product is + 20 and sum is - 9

x² - 9x + 20

∧

-1 - 20 = - 21

-2 - 10 = - 12

-4 - 5 = - 9 ←

The numbers that go inside the parentheses will be: - 4 and - 5

(x - 4) (x - 5)
