Question

$${ x }^{ 3 } -3 { x }^{ 2 } +x+2/-1$$

Differentiate w.r.t. x

$3x^{2}-6x+1$

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 $nax^{n-1}$.

$$3x^{3-1}+2\left(-3\right)x^{2-1}+x^{1-1}$$

Subtract $1$ from $3$.

$$3x^{2}+2\left(-3\right)x^{2-1}+x^{1-1}$$

Multiply $2$ times $-3$.

$$3x^{2}-6x^{2-1}+x^{1-1}$$

Subtract $1$ from $2$.

$$3x^{2}-6x^{1}+x^{1-1}$$

Subtract $1$ from $1$.

$$3x^{2}-6x^{1}+x^{0}$$

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

$$3x^{2}-6x+x^{0}$$

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

$$3x^{2}-6x+1$$

Evaluate

$x^{3}-3x^{2}+x-2$
