Answer:
3x^2 -2x+1
Step-by-step explanation:
5x^2 -2x+2 -(2x^2 +1)
Distribute the minus sign
5x^2 -2x+2 -2x^2 -1=
3x^2 -2x+1
Remember the large squares are x^2 , the rectangle are x and the small squares are 1
The colored tiles are positive and the white tiles are negative
5x^2 -2x+2 is 5 colored large squares, 2 white rectangles 2 colored small squares
-2x^2 -1 is 2 white large squares and 1 white small square
Add them together
3x^2 -2x+1 3 colored large squares, 2 white squares and 1 colored small square
