Solve -3R(-2R)

$$- 3 R ( - 2 R )$$

Evaluate

$$6R^{2}$$

Solution Steps

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

$$-3R^{2}\left(-2\right)$$

Multiply -3 and -2 to get 6.

$$6R^{2}$$

Differentiate w.r.t. R

$$12R$$

Steps Using Definition of a Derivative

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

$$\frac{\mathrm{d}}{\mathrm{d}R}(-3R^{2}\left(-2\right))$$

Multiply -3 and -2 to get 6.

$$\frac{\mathrm{d}}{\mathrm{d}R}(6R^{2})$$

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

$$2\times 6R^{2-1}$$

Multiply 2 times 6.

$$12R^{2-1}$$

Subtract 1 from 2.

$$12R^{1}$$

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

$$12R$$
