expand ((80-x)*x)/4

expand

\frac{( 80 - x ) \cdot x}{4}

- \frac{x ^{2}}{4} + 20 x

Solution steps

\frac{( 80 - x ) x}{4}

Expand

(80 - x) x : 80 x - x^{2}

= \frac{80 x - x ^{2}}{4}

Apply the fraction rule:

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

\frac{80 x - x ^{2}}{4} = \frac{80 x}{4} - \frac{x ^{2}}{4}

= \frac{80 x}{4} - \frac{x ^{2}}{4}

Divide the numbers:

\frac{80}{4} = 20

= 20 x - \frac{x ^{2}}{4}

Rewrite in standard form

= - \frac{x ^{2}}{4} + 20 x

(3 sin (π x) - 2 sin (5 π x)) sin (\frac{nπ x}{20})

2 (x + y i)^{2}

\frac{z + 16}{z ^{2} ( z - 1 )}

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

\frac{x ( s + 12 )}{s ^{2} + 12 s + 36}
