Answer:
So the area of the shaded region is 10x^2+6x-12
Explanation:
So let's break this up, you need to multiply x+4 and x+2 together and x+1 and x+1 together:
x+4 X x+2= x^2+6x+8
x+1 X x+1= x^2+2x+1
After you have done that add the two products together:
x^2+6x+8+x^2+2x+1= 2x^2+8x+9
Then multiply 2x+3 and 6x-1 together:
2x+3 X 6x-1= 12x^2+16x-3
After that you need to subtract 12x^2+16x-3 and 2x^2+8x+9:
12x^2+16x-3 - (2x^2+8x+9)= 10x^2+6x-12
Answer: 10x^2+6x-12
Hope this helps!
