how did you get your answer
 
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?
 
3.13(1+x)^2 = 4.32

x= .1748

i was wondering if u guys can show me the steps to get the x number

I thought I just did.
 
sorry i did not read your post correctly. thanks for the help. i got it now
 
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.
