Solve 0a+0+1-4a

$$0 a + 0 + 1 - 4 a$$

Evaluate

$$1-4a$$

Solution Steps

Anything times zero gives zero.

$$0+0+1-4a$$

Add 0 and 0 to get 0.

$$1-4a$$

Differentiate w.r.t. a

$$-4$$

Steps Using Derivative Rule for Sum

Anything times zero gives zero.

$$\frac{\mathrm{d}}{\mathrm{d}a}(0+0+1-4a)$$

Add 0 and 0 to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(1-4a)$$

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}.

$$-4a^{1-1}$$

Subtract 1 from 1.

$$-4a^{0}$$

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

$$-4$$
