simplify 2/x-x^2+1

Solution

simplify

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

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

Solution steps

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

Convert

x^{2}

to fraction

: \frac{x ^{3}}{x}

Convert

1

to fraction

: \frac{x}{x}

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

Apply the fraction rule:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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

\frac{x ^{2}}{x + 4}

(\frac{b}{a + z ^{2}})^{4}

n = 0 \sum \infty (0.4)^{n}

\int \frac{2 z - 5}{7} d z

\int (\frac{x ^{3} - 2 x ^{2} + 4 x}{x}) d x
