Solve x^2x^5+x^2-2xx^2+4x+4

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

Evaluate

$$x^{7}-2x^{3}+\left(x+2\right)^{2}$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 2 and 5 to get 7.

$$x^{7}+x^{2}-2xx^{2}+4x+4$$

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$x^{7}+x^{2}-2x^{3}+4x+4$$

Differentiate w.r.t. x

$$7x^{6}-6x^{2}+2x+4$$
