Basic Math Examples

$3 y^{2} - 5 y + 7 + (- 2 + 6 y - 7 y^{2})$

Step 1

Remove parentheses.

$3 y^{2} - 5 y + 7 - 2 + 6 y - 7 y^{2}$

Step 2

Subtract $7 y^{2}$ from $3 y^{2}$ .

$- 4 y^{2} - 5 y + 7 - 2 + 6 y$

Step 3

Add $- 5 y$ and $6 y$ .

$- 4 y^{2} + y + 7 - 2$

Step 4

Subtract $2$ from $7$ .

$- 4 y^{2} + y + 5$

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