4/(x-1)-4/(x+1)=1

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

x = 3, x = - 3

Solution steps

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

Multiply by LCM

4 (x + 1) - 4 (x - 1) = (x - 1) (x + 1)

Solve

4 (x + 1) - 4 (x - 1) = (x - 1) (x + 1) : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 1, x = - 1

Combine undefined points with solutions:

x = 3, x = - 3

2 x - \frac{8192}{x ^{2}} = 0

\frac{4}{y - 1} - \frac{5}{y + 2} = \frac{3}{y}

2 - \frac{98}{x ^{2}} = 0

\frac{1}{15} = \frac{1}{20} + \frac{1}{x}

\frac{1}{m} = \frac{m - 34}{2 m ^{2}}
