expand (u^3(u-4))/4

Solution

expand

\frac{u ^{3} ( u - 4 )}{4}

Solution

\frac{u ^{4}}{4} - u^{3}

Solution steps

\frac{u ^{3} ( u - 4 )}{4}

Expand

u^{3} (u - 4) : u^{4} - 4 u^{3}

= \frac{u ^{4} - 4 u ^{3}}{4}

Apply the fraction rule:

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

\frac{u ^{4} - 4 u ^{3}}{4} = \frac{u ^{4}}{4} - \frac{4 u ^{3}}{4}

= \frac{u ^{4}}{4} - \frac{4 u ^{3}}{4}

Divide the numbers:

\frac{4}{4} = 1

= \frac{u ^{4}}{4} - u^{3}
