Solve 2(1/x^2)-3

$$2( \frac{ 1 }{ { x }^{ 2 } } )-3$$

Evaluate

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

Short Solution Steps

Express 2\times \frac{1}{x^{2}} as a single fraction.

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

To add or subtract expressions, expand them to make their denominators the same. Multiply 3 times \frac{x^{2}}{x^{2}}.

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

Since \frac{2}{x^{2}} and \frac{3x^{2}}{x^{2}} have the same denominator, subtract them by subtracting their numerators.

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

Factor

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