Can someone help me please

To simplify this expression, we combine all the like terms. We cannot solve for x because there is no equal sign and/or no value for x.

Equation: (10x² - 10x - 6) + (x + 6)

-10x and x are like terms. Remember: there is an invisible 1 behind the variable x. We add these like normal numbers.

-6 and 6 are also like terms. Again, we add them as written.

Since our answer is 0, we do not have to write it in our simplified expression.

Now, let's add the terms together. Since 10x² doesn't have any like terms, we just let it be. We take our previous number, -9x, and we add it to 10x².
