expand ((-12-2x)(70x+420))/x

expand

\frac{( - 12 - 2 x ) ( 70 x + 420 )}{x}

- 140 x - 1680 - \frac{5040}{x}

Solution steps

\frac{( - 12 - 2 x ) ( 70 x + 420 )}{x}

Expand

(- 12 - 2 x) (70 x + 420) : - 140 x^{2} - 1680 x - 5040

= \frac{- 140 x ^{2} - 1680 x - 5040}{x}

Apply the fraction rule:

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

\frac{- 140 x ^{2} - 1680 x - 5040}{x} = - \frac{140 x ^{2}}{x} - \frac{1680 x}{x} - \frac{5040}{x}

= - \frac{140 x ^{2}}{x} - \frac{1680 x}{x} - \frac{5040}{x}

Cancel

\frac{140 x ^{2}}{x} : 140 x

= - 140 x - \frac{1680 x}{x} - \frac{5040}{x}

Cancel

\frac{1680 x}{x} : 1680

= - 140 x - 1680 - \frac{5040}{x}

\frac{h - 2}{2 ( 1 + 2 h )}

y (x y + y) (x - 1) y^{'} (x)

(e^{x y} + e^{y})^{4}

\frac{1}{12} e^{4 x} (2 x - 1)

(x ln (x) + x y) d y
