Question

$${ a }^{ 2 } +3a+9$$

Differentiate w.r.t. a

$2a+3$

Steps Using Derivative Rule for Sum

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 $nax^{n-1}$.

$$2a^{2-1}+3a^{1-1}$$

Subtract $1$ from $2$.

$$2a^{1}+3a^{1-1}$$

Subtract $1$ from $1$.

$$2a^{1}+3a^{0}$$

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

$$2a+3a^{0}$$

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

$$2a+3\times 1$$

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

$$2a+3$$

Evaluate

$a^{2}+3a+9$
