Answer
-15x + 7
Work Step by Step
the translation is
( $x^{2}$ - 9x + 2 ) + (2 $x^{2}$ -6x + 1 ) - ( 3$x^{2}$ -4)
( $x^{2}$ - 9x + 2 ) + (2 $x^{2}$ -6x + 1 ) + ( - 3$x^{2}$ + 4)
add the opposite
$x^{2}$ - 9x + 2 + 2 $x^{2}$ -6x + 1 - 3$x^{2}$ +4
combine like terms
$x^{2}$ + 2 $x^{2}$ - 3$x^{2}$ - 9x - 6x + 2 + 1+ 4
- 15x + 7
