$$3x(2x)$$

Evaluate

$$6x^{2}$$

Solution Steps

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

$$3x^{2}\times 2$$

Multiply 3 and 2 to get 6.

$$6x^{2}$$

Differentiate w.r.t. x

$$12x$$

Steps Using Definition of a Derivative

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(3x^{2}\times 2)$$

Multiply 3 and 2 to get 6.

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

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

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

Multiply 2 times 6.

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

Subtract 1 from 2.

$$12x^{1}$$

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

$$12x$$
