## Algebra: A Combined Approach (4th Edition)

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
