Solve 2-1/-x^2

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

Evaluate

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

Short Solution Steps

Factor -x^{2}.

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

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

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

Since \frac{2\left(-1\right)x^{2}}{-x^{2}} and \frac{1}{-x^{2}} have the same denominator, subtract them by subtracting their numerators.

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

Do the multiplications in 2\left(-1\right)x^{2}-1.

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

Factor

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