Answer:
-4x*2 - 7y*2 + 4
Step-by-step explanation:
simplify by adding/subtracting the like terms
Answer:
-4x^2 +4 -7y^2
Step-by-step explanation:
If you are talking about simplifying you would need to combine like terms. It isn't really hard, just combining like terms. It could be like this:
4x^2 (Stays the same because there are no other like terms for it.)
-3+4+3= -3+7=4
-5y^2 +3y^2 -5y^2 = -2y^2 -5y^2 = -7y^2
So it would be 4x^2 +4 -7y^2
I hope this helps, I am not sure if this is what you need.
