Question

$$3a+7-12-a$$

Evaluate

$2a-5$

Differentiate w.r.t. a

$2$

Steps Using Derivative Rule for Sum

Subtract $12$ from $7$ to get $-5$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(3a-5-a)$$

Combine $3a$ and $-a$ to get $2a$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(2a-5)$$

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 $nax^{n-1}$.

$$2a^{1-1}$$

Subtract $1$ from $1$.

$$2a^{0}$$

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

$$2\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$2$$
