Simplify 12x+4y-3x+2-8y^2+3^2

$12 x + 4 y - 3 x + 2 - 8 y^{2} + 3^{2}$

Step 1

Raise $3$ to the power of $2$ .

$12 x + 4 y - 3 x + 2 - 8 y^{2} + 9$

Step 2

Subtract $3 x$ from $12 x$ .

$9 x + 4 y + 2 - 8 y^{2} + 9$

Step 3

Simplify the expression.

Add $2$ and $9$ .

$9 x + 4 y - 8 y^{2} + 11$

Move $4 y$ .

$9 x - 8 y^{2} + 4 y + 11$

Reorder $9 x$ and $- 8 y^{2}$ .

$- 8 y^{2} + 9 x + 4 y + 11$

$- 8 y^{2} + 9 x + 4 y + 11$
