Question

$$( { x }^{ 2 } -7x-4)/x+4$$

Evaluate

$x-3-\frac{4}{x}$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply $4$ times $\frac{x}{x}$.

$$\frac{x^{2}-7x-4}{x}+\frac{4x}{x}$$

Since $\frac{x^{2}-7x-4}{x}$ and $\frac{4x}{x}$ have the same denominator, add them by adding their numerators.

$$\frac{x^{2}-7x-4+4x}{x}$$

Combine like terms in $x^{2}-7x-4+4x$.

$$\frac{x^{2}-3x-4}{x}$$

Expand

$x-3-\frac{4}{x}$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply $4$ times $\frac{x}{x}$.

$$\frac{x^{2}-7x-4}{x}+\frac{4x}{x}$$

Since $\frac{x^{2}-7x-4}{x}$ and $\frac{4x}{x}$ have the same denominator, add them by adding their numerators.

$$\frac{x^{2}-7x-4+4x}{x}$$

Combine like terms in $x^{2}-7x-4+4x$.

$$\frac{x^{2}-3x-4}{x}$$
