inverse of 3/(x^2+2x)

inverse

\frac{3}{x ^{2} + 2 x}

\frac{- x + x ( x + 3 )}{x}, - \frac{x + x ( x + 3 )}{x}

Solution steps

y = \frac{3}{x ^{2} + 2 x}

Replace

x

with

y

x = \frac{3}{y ^{2} + 2 y}

Solve for

y, x = \frac{3}{y ^{2} + 2 y}

\frac{- x + x ( x + 3 )}{x}, - \frac{x + x ( x + 3 )}{x}

f (x) = x (34 - x)

f (x) = \frac{10 x}{x ^{2} + 25}

f (x) = 3 x^{2} + 7
