Question

$$-7x \times 5x$$

Evaluate

$-35x^{2}$

Show Solution

Differentiate w.r.t. x

$-70x$

Steps Using Definition of a Derivative

Multiply $x$ and $x$ to get $x^{2}$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-7x^{2}\times 5)$$

Multiply $-7$ and $5$ to get $-35$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-35x^{2})$$

The derivative of $ax^{n}$ is $nax^{n-1}$.

$$2\left(-35\right)x^{2-1}$$

Multiply $2$ times $-35$.

$$-70x^{2-1}$$

Subtract $1$ from $2$.

$$-70x^{1}$$

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

$$-70x$$
