Question

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

Evaluate

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

Solution Steps

Combine $x$ and $-4x$ to get $-3x$.

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

Combine $3y$ and $-4y$ to get $-y$.

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

Combine $x^{2}$ and $2x^{2}$ to get $3x^{2}$.

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

Combine $y^{2}$ and $2y^{2}$ to get $3y^{2}$.

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

Differentiate w.r.t. x

$6x-3$
