Question

6xy²+(-3x'y²) when simplified is:

-18xy².
-3x3у².
3x3у²
None of the choices are correct.

Answer 1

3xy²

Explanation:

6xy² and 3xy² are the same, except for the number in the front. Remove the same elements from each number, which is the x and y^2, and it turns into 6 - 3. All you do is add the similar elements.

6xy² - 3xy² = 3xy²
