Step 1.1

Subtract $3$ from $20$ .

$3 x y + 17 + 4 y^{2} + 10 - 2 y^{2}$

Step 1.2

Add $17$ and $10$ .

$3 x y + 4 y^{2} + 27 - 2 y^{2}$

$3 x y + 4 y^{2} + 27 - 2 y^{2}$

Step 2

Subtract $2 y^{2}$ from $4 y^{2}$ .

$3 x y + 2 y^{2} + 27$

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