expand-(2(-2x-3))/(x^4)

expand

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

\frac{4}{x ^{3}} + \frac{6}{x ^{4}}

Solution steps

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

Expand

2 (- 2 x - 3) : - 4 x - 6

= - \frac{- 4 x - 6}{x ^{4}}

Apply the fraction rule:

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

\frac{- 4 x - 6}{x ^{4}} = - (- \frac{4 x}{x ^{4}}) - (- \frac{6}{x ^{4}})

= - (- \frac{4 x}{x ^{4}}) - (- \frac{6}{x ^{4}})

Apply rule

- (- a) = a

= \frac{4 x}{x ^{4}} + \frac{6}{x ^{4}}

Cancel

\frac{4 x}{x ^{4}} : \frac{4}{x ^{3}}

= \frac{4}{x ^{3}} + \frac{6}{x ^{4}}

h (t - 4) \cdot e^{t - 4}

(6 x + 4 z = 36) 2

e^{x} (a cos (x) + b sin (x))

n o t ab l es (2 - 5 x) (5 x + 2)

\frac{6 ( x + h ) + 5}{5 ( x + h ) - 6}
