Step-by-step explanation:

Total area      -   interior area   = shaded area

(4x-2)(x+3)     -   ( x (x+2))   =

4x^2 + 10x -6     -  x^2 - 2x =

3x^2 + 8x - 6    = shaded area

Area of unshaded region:

(x+2)(x) = x²+2x

Area of shaded rectangle:

(4x-2)(x+3) = 4x²+10x-6

Area of shaded region:

(4x²+10x-6) - (x²+2x) = 3x²+8x-6
