Question

$$x^{2}+2\sqrt{5}x-15$$

Differentiate w.r.t. x

$2\left(x+\sqrt{5}\right)$

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 $nax^{n-1}$.

$$2x^{2-1}+2\sqrt{5}x^{1-1}$$

Subtract $1$ from $2$.

$$2x^{1}+2\sqrt{5}x^{1-1}$$

Subtract $1$ from $1$.

$$2x^{1}+2\sqrt{5}x^{0}$$

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

$$2x+2\sqrt{5}x^{0}$$

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

$$2x+2\sqrt{5}\times 1$$

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

$$2x+2\sqrt{5}$$

Evaluate

$x^{2}+2\sqrt{5}x-15$
