Answer:
7x^2 - 16x + 5
Step-by-step explanation:
find the area of the unshaded box
(3x + 1) (x + 1) =
3x^2 + 3x + x +1 or 3x^2 + 4x + 1
whole shaded ares
(2x - 3) (5x - 2) =
10x^2 - 4x - 8x +6 or 10x^2 - 12x + 6
whole shaded area minus the unshaded area
10x^2 - 12x + 6
- 3x^2 + 4x + 1
7x^2 - 16x + 5
