expand (x+18)/(x(x+3)(x+15)(x+20))

expand

\frac{x + 18}{x ( x + 3 ) ( x + 15 ) ( x + 20 )}

\frac{x + 18}{x ^{4} + 38 x ^{3} + 405 x ^{2} + 900 x}

Solution steps

\frac{x + 18}{x ( x + 3 ) ( x + 15 ) ( x + 20 )}

Expand

x (x + 3) (x + 15) (x + 20) : x^{4} + 38 x^{3} + 405 x^{2} + 900 x

= \frac{x + 18}{x ^{4} + 38 x ^{3} + 405 x ^{2} + 900 x}

\frac{20 ( s + 1.5 )}{s ^{3} + 10.5 s ^{2} + 25 s + 30}

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

- (x^{4} + x^{3} - 6 x^{2} - 4 x + 8 = 0)

(2 + \frac{3 i}{n})^{2}

(x + 1 - 2)^{2}
