expand ((4+x)(x-2))/x

expand

\frac{( 4 + x ) ( x - 2 )}{x}

2 + x - \frac{8}{x}

Solution steps

\frac{( 4 + x ) ( x - 2 )}{x}

Expand

(4 + x) (x - 2) : 2 x + x^{2} - 8

= \frac{2 x + x ^{2} - 8}{x}

Apply the fraction rule:

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

\frac{2 x + x ^{2} - 8}{x} = \frac{2 x}{x} + \frac{x ^{2}}{x} - \frac{8}{x}

= \frac{2 x}{x} + \frac{x ^{2}}{x} - \frac{8}{x}

Cancel

\frac{2 x}{x} : 2

= 2 + \frac{x ^{2}}{x} - \frac{8}{x}

Cancel

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

= 2 + x - \frac{8}{x}

(1 - x + 2)^{2}

\frac{2 ^{i} ( 2 ^{k - i} - 1 ) ^{2}}{2 ^{k} - 1}

12 (\frac{2}{3} x + 7)

(a + b c) (a - b c)

(4 - x 7)^{2}
