Answer:
5x^2 - 20x - 31
Explanation:
2x +3(4x-5) = 8x^2 + 2x - 15
3x + 2(x - 8) = 3x^2 - 22x - 16
8x^2 + 2x - 15 - 3x^2 - 22x - 16 = 5x^2 - 20x - 31
The shaded region is 5x^2 - 20x - 31
5x+1
2x+3
*4x-5
=8x-15
Now you find the area of the white region
3x+2
*2-8
=3x+16
Now you subtract
8x-15
-3x+16
=5x+1
