For this case we have the following equation:
[tex]x + 1 = \frac {2} {x + 1}[/tex]
We must find the value of [tex]x + 1[/tex]:
Multiplying both sides of the equation by[tex]x + 1:[/tex]
[tex](x + 1) ^ 2 = 2[/tex]
Applying square root on both sides of the equation to eliminate the exponent:
[tex]x + 1 = \sqrt {2}[/tex]
Answer:
Option B
