3/(x+1)-1/(x^2-1)=0

\frac{3}{x + 1} - \frac{1}{x ^{2} - 1} = 0

x = \frac{4}{3}

Decimal Notation

x = 1.33333 \dots

Solution steps

\frac{3}{x + 1} - \frac{1}{x ^{2} - 1} = 0

Multiply by LCM

3 (x - 1) - 1 = 0

Move

1

to the right side

3 (x - 1) = 1

Divide both sides by

3

x - 1 = \frac{1}{3}

Move

1

to the right side

x = \frac{4}{3}

Verify Solutions

Find undefined (singularity) points:

x = - 1, x = 1

Combine undefined points with solutions:

x = \frac{4}{3}

\frac{x + 1}{x - 2} + \frac{2 x}{x + 2} + 2 = 0

x - \frac{1}{x - 1} = \frac{5}{x - 1}

\frac{r - 4}{3 r} = \frac{1}{5 r} + 1

\frac{7}{x} = \frac{2}{3}

\frac{x ^{2}}{x + 2} = \frac{4}{x + 2}
