Differentiate w.r.t. a

$$-1$$

Steps Using Derivative Rule for Sum

Add 6 and 0 to get 6.

$$\frac{\mathrm{d}}{\mathrm{d}a}(6-a-2+8)$$

Subtract 2 from 6 to get 4.

$$\frac{\mathrm{d}}{\mathrm{d}a}(4-a+8)$$

Add 4 and 8 to get 12.

$$\frac{\mathrm{d}}{\mathrm{d}a}(12-a)$$

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}.

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

Subtract 1 from 1.

$$-a^{0}$$

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