Welcome to PF.

Not sure your method, but I get something different.

Plugging in your value I get 4.096 = 4.32

Maybe try taking the square root of both sides of

(1+x)2 = 4.32/3.13

And then solving simply?

To solve this correctly you need to expand and simplify and then use the quadratic formula to find x. There are two solutions to this equation.
