Another math problem, i really, really need help with this one -4x^2-3+4+3-5y^2+3y^2-5y^2

-4x*2 - 7y*2 + 4

Step-by-step explanation:

simplify by adding/subtracting the like terms

-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.

step-by-step explanation: yes
