expand (5x-1)/((x+1)(1+x+3x^2))

expand

\frac{5 x - 1}{( x + 1 ) ( 1 + x + 3 x ^{2} )}

\frac{5 x - 1}{3 x ^{3} + 4 x ^{2} + 2 x + 1}

Solution steps

\frac{5 x - 1}{( x + 1 ) ( 1 + x + 3 x ^{2} )}

Expand

(x + 1) (1 + x + 3 x^{2}) : 3 x^{3} + 4 x^{2} + 2 x + 1

= \frac{5 x - 1}{3 x ^{3} + 4 x ^{2} + 2 x + 1}

\frac{x}{( 3 x ^{2} + 2 ) ( 6 + 3 x ^{2} t + 2 t )}

(3 x + \frac{6}{x})^{8}

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

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

x^{6} l e f t (x^{2} + 4 x)
