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 is the answer!

Hope this helps.

Step by step:

Just ask! I will add it here :)

Answer 2

Answer:

$9x^{2} - 12y^{2} - 11x$

Step-by-step 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!
