expand ((x+1)(2x+1))/(10x(x-3))

expand

\frac{( x + 1 ) ( 2 x + 1 )}{10 x ( x - 3 )}

\frac{2 x ^{2} + 3 x + 1}{10 x ^{2} - 30 x}

Solution steps

\frac{( x + 1 ) ( 2 x + 1 )}{10 x ( x - 3 )}

Expand

10 x (x - 3) : 10 x^{2} - 30 x

= \frac{( x + 1 ) ( 2 x + 1 )}{10 x ^{2} - 30 x}

Expand

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

= \frac{2 x ^{2} + 3 x + 1}{10 x ^{2} - 30 x}

2 \frac{d}{d x} (w (1 - x))

\frac{- 5 x - 19}{( x - 1 ) ( x - 7 )}

v (2 - sin (\frac{π ( t - 60 )}{120}))

2 (3 x^{2} + 2 x - 10)^{2}

\frac{4}{5 ( 20 x - 10 )}
