Solve {l}{-a^2}{+2a^2}

$$\left. \begin{array} { l } { - a ^ { 2 } } \\ { + 2 a ^ { 2 } } \end{array} \right.$$

Differentiate w.r.t. a

$$2a$$

Steps Using Definition of a Derivative

Combine -a^{2} and 2a^{2} to get a^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a^{2})$$

The derivative of ax^{n} is nax^{n-1}.

$$2a^{2-1}$$

Subtract 1 from 2.

$$2a^{1}$$

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

$$2a$$

Evaluate

$$a^{2}$$

Solution Steps

Combine -a^{2} and 2a^{2} to get a^{2}.

$$a^{2}$$
