Question

Subtract (-2z^2 - 14 ) - (-12z^2 ).

Answer 1

To subtract (-2z^2 - 14) - (-12z^2), distribute the negative sign to the terms inside the parentheses, and then combine like terms.

Step-by-step explanation:

To subtract (-2z^2 - 14) - (-12z^2), we need to distribute the negative sign to the terms inside the parentheses. This gives us -2z^2 - 14 + 12z^2.

Now, we can combine like terms by adding the coefficients of the like terms.

So, (-2z^2 + 12z^2) - 14 gives us 10z^2 - 14.

Therefore, the final answer is 10z^2 - 14.
