Question

$$4+2x-5+2x$$

Evaluate

$4x-1$

Differentiate w.r.t. x

$4$

Steps Using Derivative Rule for Sum

Subtract $5$ from $4$ to get $-1$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-1+2x+2x)$$

Combine $2x$ and $2x$ to get $4x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-1+4x)$$

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 $nax^{n-1}$.

$$4x^{1-1}$$

Subtract $1$ from $1$.

$$4x^{0}$$

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

$$4\times 1$$

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

$$4$$
