$4 x^{2} - 5 x + 23 + (3 x^{2} + 8 x - 87)$

Step 1

Remove parentheses.

$4 x^{2} - 5 x + 23 + 3 x^{2} + 8 x - 87$

Step 2

Add $4 x^{2}$ and $3 x^{2}$ .

$7 x^{2} - 5 x + 23 + 8 x - 87$

Step 3

Add $- 5 x$ and $8 x$ .

$7 x^{2} + 3 x + 23 - 87$

Step 4

Subtract $87$ from $23$ .

$7 x^{2} + 3 x - 64$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
