Solve -2w*2w

$$- 2 w \cdot 2 w$$

Evaluate

$$-4w^{2}$$

Solution Steps

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

$$-2w^{2}\times 2$$

Multiply -2 and 2 to get -4.

$$-4w^{2}$$

Differentiate w.r.t. w

$$-8w$$

Steps Using Definition of a Derivative

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

$$\frac{\mathrm{d}}{\mathrm{d}w}(-2w^{2}\times 2)$$

Multiply -2 and 2 to get -4.

$$\frac{\mathrm{d}}{\mathrm{d}w}(-4w^{2})$$

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

$$2\left(-4\right)w^{2-1}$$

Multiply 2 times -4.

$$-8w^{2-1}$$

Subtract 1 from 2.

$$-8w^{1}$$

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

$$-8w$$
