Solve the following equation. If the equation has no​ solution so state.

1/x-1 + 1/x+1 = 2/x^2-1

1 answer

To solve the equation 1/x-1 + 1/x+1 = 2/x^2-1, we can start by finding a common denominator for the fractions on the left side.

The common denominator for 1/(x-1) and 1/(x+1) is (x-1)(x+1). Rewriting the equation with this common denominator, we have:

[(x+1)+(x-1)] / (x-1)(x+1) = 2/(x^2-1)

Simplifying the numerator and denominator:

[2x] / (x-1)(x+1) = 2/(x^2-1)

Now, we can cancel out the (x^2-1) terms:

[2x] / (x-1)(x+1) = 2/[(x-1)(x+1)]

Since the numerators (2x) and the denominators (x-1)(x+1) are the same on both sides, we can equate them:

2x = 2

Solving for x:

2x = 2
x = 1

Therefore, the solution to the equation is x = 1.
