Question
Perform the indicated operations.$$\left(-6 x^{2}+2 x+5\right)-\left(4 x^{2}+4 x-1\right)+\left(7 x^{2}+4\right)$$
Step 1
Step 1: First, distribute the subtraction sign to the terms in the second parentheses: $$ \left(-6 x^{2}+2 x+5\right)-\left(4 x^{2}+4 x-1\right)+\left(7 x^{2}+4\right) = -6 x^{2}+2 x+5 - 4 x^{2}-4 x+1 +7 x^{2}+4 $$ Show more…
