Question

$${ x }^{ 2 } -8 \div x-2$$

Evaluate

$x^{2}-2-\frac{8}{x}$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply $x^{2}-2$ times $\frac{x}{x}$.

$$\frac{\left(x^{2}-2\right)x}{x}-\frac{8}{x}$$

Since $\frac{\left(x^{2}-2\right)x}{x}$ and $\frac{8}{x}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{\left(x^{2}-2\right)x-8}{x}$$

Do the multiplications in $\left(x^{2}-2\right)x-8$.

$$\frac{x^{3}-2x-8}{x}$$

Factor

$\frac{x^{3}-2x-8}{x}$
