Question

$$7 { x }^{ 2 } +Kx-3$$

Differentiate w.r.t. x

$14x+K$

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 $nax^{n-1}$.

$$2\times 7x^{2-1}+Kx^{1-1}$$

Multiply $2$ times $7$.

$$14x^{2-1}+Kx^{1-1}$$

Subtract $1$ from $2$.

$$14x^{1}+Kx^{1-1}$$

Subtract $1$ from $1$.

$$14x^{1}+Kx^{0}$$

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

$$14x+Kx^{0}$$

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

$$14x+K\times 1$$

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

$$14x+K$$

Evaluate

$7x^{2}+Kx-3$
