Answer:

A= 8

B= -5

C= -14

Explanation:

Area of Rectangle = length * width

Area of the shaded Rectangle:

Area = l * w

Area= (4x + 1) (3x - 5)

Open the brackets

A= 12x^2 - 20x + 3x - 5

A = 12x^2 - 17x - 5

Area of the Unshaded:

The Unshaded portion is a square. Hence, it's area = l^ 2

Area = (2x - 3) ( 2x - 3)

A= 4x^2 - 6x - 6x + 9

A= 4x^2 - 12x + 9

To get the exact shaded portion

A(Shaded) = (12x^2 - 17x - 5) - ( 4x^2 - 12x + 9)

Area = 8x^2 - 5x - 14

A= 8

B= -5

C= -14
