Question

What is the sum of the polynomials
(8x^2-9y^2-4x) + (x^2-3y^2-7x)

Answer 1

`9x^(2) - 12y^(2) - 11x`

Explanation:

`(8x^(2) - 9y^(2) - 4x) + (x^(2) - 3y^(2) -7x)\\(8x^(2) + x^(2) ) + (-9y^(2) - 3y^(2) ) + (-4x - 7x)\\9x^(2) - 12y^(2) - 11x`

In the first step, I rearranged the equation and put like terms together.

Then I just combined the like terms.

I hope this helps!

Answer 2

9x^2-12y^2-11x is the answer!
