Question

$$4 \cdot x ^ { 2 } - 2 x + 1$$

Differentiate w.r.t. x

$8x-2$

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 $nax^{n-1}$.

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

Multiply $2$ times $4$.

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

Subtract $1$ from $2$.

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

Subtract $1$ from $1$.

$$8x^{1}-2x^{0}$$

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

$$8x-2x^{0}$$

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

$$8x-2$$

Evaluate

$4x^{2}-2x+1$
