Question

$$x+x-1$$

Differentiate w.r.t. x

$2$

Steps Using Derivative Rule for Sum

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

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

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 $nax^{n-1}$.

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

Subtract $1$ from $1$.

$$2x^{0}$$

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

$$2\times 1$$

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

$$2$$

Evaluate

$2x-1$
