Question

Find the product
(4x-5)(4x-1)

Answer 1

16x² - 24x + 5

Explanation:

Given

(4x - 5)(4x - 1)

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

4x(4x - 1) - 5(4x - 1) ← distribute both parenthesis

= 16x² - 4x - 20x + 5 ← collect like terms

= 16x² - 24x + 5

Answer 2

80

(4x-5)(4x-1) = 80
