Solve x2-1(-1)

$$x 2 - 1 ( - 1 )$$

Evaluate

$$x_{2}+1$$

Solution Steps

Multiply 1 and -1 to get -1.

$$x_{2}-\left(-1\right)$$

The opposite of -1 is 1.

$$x_{2}+1$$

Differentiate w.r.t. x_2

$$1$$

Steps Using Derivative Rule for Sum

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$x_{2}^{1-1}$$

Subtract 1 from 1.

$$x_{2}^{0}$$

For any term t except 0, t^{0}=1.

$$1$$
