Answer 1

11x² - 23x - 14

Explanation:

The area left is the area of the outer rectangle subtract the square, that is

A = (4x + 1)(3x - 5) - (x + 3)² ← expand factors using FOIL

= 12x² - 17x - 5 - (x² + 6x + 9) ← distribute parenthesis by - 1

= 12x² - 17x - 5 - x² - 6x - 9 ← collect like terms

= 11x² - 23x - 14

Answer 2

answer- 11x^2 - 11x + 4

k so you do (4x + 1) x (3x - 5) = 12x^2 - 20x + 3x - 5 = 12x^2 - 17x - 5
(x + 3)^2 = x^2 + 6x + 9
(12x^2 - 17x - 5) - (x^2 + 6x + 9)
11x^2 - 11x + 4
