Solve =5x^4-11x-9/x^4

$$= 5 x ^ { 4 } - 11 x - \frac { 9 } { x ^ { 4 } }$$

Evaluate

$$5x^{4}-11x-\frac{9}{x^{4}}$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 5x^{4}-11x times \frac{x^{4}}{x^{4}}.

$$\frac{\left(5x^{4}-11x\right)x^{4}}{x^{4}}-\frac{9}{x^{4}}$$

Since \frac{\left(5x^{4}-11x\right)x^{4}}{x^{4}} and \frac{9}{x^{4}} have the same denominator, subtract them by subtracting their numerators.

$$\frac{\left(5x^{4}-11x\right)x^{4}-9}{x^{4}}$$

Do the multiplications in \left(5x^{4}-11x\right)x^{4}-9.

$$\frac{5x^{8}-11x^{5}-9}{x^{4}}$$

Factor

$$\frac{5x^{8}-11x^{5}-9}{x^{4}}$$
