Question

30 POINTS! x + 1 = 2 ÷ x + 1

In the equation above, which choice is a possible value of x + 1?

A) 1 - √2

B) √2

C) 2

D) 4

Answer 1

Answer: B

Explanation:

Answer 2

For this case we have the following equation:

`x + 1 = \frac {2} {x + 1}`

We must find the value of
`x + 1`:

Multiplying both sides of the equation by
`x + 1:`

`(x + 1) ^ 2 = 2`

Applying square root on both sides of the equation to eliminate the exponent:

`x + 1 = \sqrt {2}`
