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

4 $y^{2}$ - 5y + 3
the translation is ( 3$y^{2}$ + y + 4 ) + ( 2$y^{2}$ - 6y - 10 ) - ( $y^{2}$ -9 ) ( 3$y^{2}$ + y + 4 ) + ( 2$y^{2}$ - 6y - 10 ) + (- $y^{2}$ +9 ) add the opposite 3$y^{2}$ + y + 4 + 2$y^{2}$ - 6y - 10 - $y^{2}$ +9 combine like terms 3$y^{2}$ + 2$y^{2}$ - $y^{2}$ + y - 6y + 4 - 10 + 9 4 $y^{2}$ - 5y + 3 simplify
