Answer:
11 x^2 + 4x -6
Step-by-step explanation:
combine like terms but be careful with the minus sign in front of the second set of parentheses.
4x^2 + 9x -7 + 7x^2 -5x +1
Answer: [tex]-3x^2+4x-6\\[/tex]
4x^2 +9x-7 does not need distributive propery
-(7x^2+5x-1) does with that negitive in front of parentheses
It then becomes -7x^2-5x+1
Add it all together
[tex]-3x^2+4x-6[/tex]
