Question

$$8 x - 7 x - 26 x - 3 x$$

Evaluate

$-28x$

Solution Steps

Combine $8x$ and $-7x$ to get $x$.

$$x-26x-3x$$

Combine $x$ and $-26x$ to get $-25x$.

$$-25x-3x$$

Combine $-25x$ and $-3x$ to get $-28x$.

$$-28x$$

Differentiate w.r.t. x

$-28$

Steps Using Definition of a Derivative

Combine $8x$ and $-7x$ to get $x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(x-26x-3x)$$

Combine $x$ and $-26x$ to get $-25x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-25x-3x)$$

Combine $-25x$ and $-3x$ to get $-28x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-28x)$$

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

$$-28x^{1-1}$$

Subtract $1$ from $1$.

$$-28x^{0}$$

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

$$-28$$
