Basic Math Examples

$y^{2} - 4 + (y^{2} + 4 y - 2)$

Step 1

Remove parentheses.

$y^{2} - 4 + y^{2} + 4 y - 2$

Step 2

Add $y^{2}$ and $y^{2}$ .

$2 y^{2} - 4 + 4 y - 2$

Step 3

Subtract $2$ from $- 4$ .

$2 y^{2} + 4 y - 6$

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