Search it up! There are lots of helpful and informative videos that can explain how to do it more than I can!
The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
