Answer

$33x^{2}$ - 80x + 7

Work Step by Step

Given the areas, we subtract both areas by one another. ($49x^{2}$ - 56x + 16)-($16x^{2}$ + 24x + 9) We distribute the negative sign to the second bracket and get $49x^{2}$ - 56x + 16 - $16x^{2}$ - 24x - 9 We add like terms together to simplify the polynomial. $49x^{2}$ - $16x^{2}$ - 24x - 56x + 16 - 9 $33x^{2}$ - 80x + 7
