Question

$$4 { x }^{ 2 } +12+9$$

Differentiate w.r.t. x

$8x$

Steps Using Derivative Rule for Sum

Add $12$ and $9$ to get $21$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(4x^{2}+21)$$

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 $nax^{n-1}$.

$$2\times 4x^{2-1}$$

Multiply $2$ times $4$.

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

Subtract $1$ from $2$.

$$8x^{1}$$

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

$$8x$$

Evaluate

$4x^{2}+21$
