Answer
-3$x^{2}$ + 16x + 4
Work Step by Step
the translation is
( $x^{2}$ + 7x + 1 ) + ( 7x + 5 ) - ( 4$x^{2}$ -2x + 2 )
( $x^{2}$ + 7x + 1 ) + ( 7x + 5 ) + ( - 4$x^{2}$ +2x - 2 ) add the opposite
$x^{2}$ + 7x + 1 + 7x + 5 - 4$x^{2}$ +2x - 2
$x^{2}$ - 4$x^{2}$ + 7x + 7x + 2x + 1 + 5 -2 combine like terms
-3$x^{2}$ + 16x + 4 simplify
