Solve x-y*x+x*x+y+x-y*x+y

$$x-y \times x+x \times x+y+x-y \times x+y$$

Evaluate

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

Solution Steps

Multiply x and x to get x^{2}.

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

Combine x and x to get 2x.

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

Combine -yx and -yx to get -2yx.

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

Combine y and y to get 2y.

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

Differentiate w.r.t. x

$$2\left(x-y+1\right)$$
