expand ((x-1)(x+3))/x

expand

\frac{( x - 1 ) ( x + 3 )}{x}

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

Solution steps

\frac{( x - 1 ) ( x + 3 )}{x}

Expand

(x - 1) (x + 3) : x^{2} + 2 x - 3

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

Apply the fraction rule:

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

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

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

Cancel

\frac{x ^{2}}{x} : x

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

Cancel

\frac{2 x}{x} : 2

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

\frac{5 x ^{3} ( x + 1 )}{12}

- \frac{3}{( 5 x + 4 ) ^{9}}
