expand (4-x)/(sqrt(1+2x))

expand

\frac{4 - x}{1 + 2 x}

\frac{( 4 - x ) 1 + 2 x}{1 + 2 x}

Solution steps

\frac{4 - x}{1 + 2 x}

Multiply by the conjugate

\frac{1 + 2 x}{1 + 2 x}

= \frac{( 4 - x ) 1 + 2 x}{1 + 2 x 1 + 2 x}

1 + 2 x 1 + 2 x = 1 + 2 x

= \frac{( 4 - x ) 1 + 2 x}{1 + 2 x}

\frac{3 e ^{- s} - 3 s ^{- 2 s}}{s ( s ^{2} - 1 )}

(3 sin (x) + cos (x))^{2}

(tan (4 x) - tan (x)) \cdot (cos (5 x) + cos (3 x))

\frac{2 x ( x ^{2} - 12 )}{( x ^{2} + 4 ) ^{3}}

(1 + 2 i)^{10}
