Answer:
find the area of the bigger rectangle, then the small one inside. Subtract the answers when finish to get the area of the shaded region
Step-by-step explanation:
Shaded region = [(2x+3)(4x-5)] - [(3x+2)(x-8)]
= [8x²-10x+12x-15 - (3x²-24x+2x-16)]
= [8x²+2x-15-(3x²-22x-16)]
= 8x²+2x-15-3x²+22x+16
= 5x²+24x+1
