Question

$$5x-2(-7)$$

Evaluate

$5x+14$

Differentiate w.r.t. x

$5$

Steps Using Derivative Rule for Sum

Multiply $2$ and $-7$ to get $-14$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(5x-\left(-14\right))$$

The opposite of $-14$ is $14$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(5x+14)$$

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 $nax^{n-1}$.

$$5x^{1-1}$$

Subtract $1$ from $1$.

$$5x^{0}$$

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

$$5\times 1$$

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

$$5$$
