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

expand

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

\frac{2 x ^{2} + 19 x - 10}{x ^{2} + x - 2}

Solution steps

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

Expand

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

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

Expand

(x + 10) (2 x - 1) : 2 x^{2} + 19 x - 10

= \frac{2 x ^{2} + 19 x - 10}{x ^{2} + x - 2}

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

\frac{1}{( 2 x + 7 ) ^{9}}

(2 m L - k + t^{2})^{2}

z + 0.016 k \cdot (z - 1) \cdot (1 - e^{- 0.5 \cdot T})

(\frac{cos ( t )}{t} - sin (t) ln (t))^{2}
