simplify (2-4/(x+2))/(5-\frac{10){x+2}}

simplify

\frac{2 - \frac{4}{x + 2}}{5 - \frac{10}{x + 2}}

\frac{2}{5}

Decimal Notation

0.4

Solution steps

\frac{2 - \frac{4}{x + 2}}{5 - \frac{10}{x + 2}}

Join

2 - \frac{4}{x + 2} : \frac{2 x}{x + 2}

= \frac{\frac{2 x}{x + 2}}{5 - \frac{10}{x + 2}}

Join

5 - \frac{10}{x + 2} : \frac{5 x}{x + 2}

= \frac{\frac{2 x}{x + 2}}{\frac{5 x}{x + 2}}

Apply the fraction rule:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

= \frac{2 x ( x + 2 )}{( x + 2 ) \cdot 5 x}

Cancel

\frac{2 x ( x + 2 )}{( x + 2 ) \cdot 5 x} : \frac{2}{5}

= \frac{2}{5}

(5 x + 2) (7 x - 2)

\frac{4}{9} b^{2} + 0.4 b c + 0.09 c^{2}

\frac{3 s ^{2}}{3 ( s ^{2} ) ^{3}}

2 f - 5 (f + 5)

(x^{2} + 2 x - 5) (x^{2} - 2 x - 1)
