inverse of (3x+4)/(x^2-25)

inverse

\frac{3 x + 4}{x ^{2} - 25}

\frac{3 + 9 - 4 x ( - 25 x - 4 )}{2 x}, \frac{3 - 9 - 4 x ( - 25 x - 4 )}{2 x}

Solution steps

y = \frac{3 x + 4}{x ^{2} - 25}

Replace

x

with

y

x = \frac{3 y + 4}{y ^{2} - 25}

Solve for

y, x = \frac{3 y + 4}{y ^{2} - 25}

\frac{3 + 9 - 4 x ( - 25 x - 4 )}{2 x}, \frac{3 - 9 - 4 x ( - 25 x - 4 )}{2 x}
