Question

(x − 6) (x − 1)
Which of the following is equivalent to the expression above?

Answer 1

x² - 7x + 6

Explanation:

(x - 6)(x - 1)

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

x(x - 1) - 6(x - 1) ← distribute both parenthesis

= x² - x - 6x + 6 ← collect like terms

= x² - 7x + 6
