Suppose you are given a rectangular piece of cardboard having length 6x−7 inches and width 5x−6 inches. Then you cut out a square from this piece of cardboard having side length 3x inches. Find the area of the remaining piece of cardboard expressed in terms of x.
It's simply the area of the piece of cardboard, less the area of the piece that's cut out, OR
Remainder = %286x+-+7%29%285x+-+6%29+-+%283x%29%5E2
Remainder = 30x%5E2+-+71x+%2B+42+-+9x%5E2
Remainder = highlight_green%2821x%5E2+-+71x+%2B+42%29
