Solve -1/x+1/x^2

$$\frac { - 1 } { x } + \frac { 1 } { x ^ { 2 } }$$

Evaluate

$$\frac{1-x}{x^{2}}$$

Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and x^{2} is x^{2}. Multiply \frac{-1}{x} times \frac{x}{x}.

$$\frac{-x}{x^{2}}+\frac{1}{x^{2}}$$

Since \frac{-x}{x^{2}} and \frac{1}{x^{2}} have the same denominator, add them by adding their numerators.

$$\frac{-x+1}{x^{2}}$$

Factor

$$\frac{1-x}{x^{2}}$$
