Answer: x^2-9x+20

Maci Preston · Answer 2

x² - 9x + 20

Step-by-step explanation:

Given

(x - 5) (x - 4)

Each term in the second factor is multiplied by each factor in the first factor, that is

x (x - 4) - 5 (x - 4) ← distribute both parenthesis

= x² - 4x - 5x + 20 ← collect like terms

= x² - 9x + 20
