 ```how do i solve this equation? (1.012)(1 + F)^2 = 1.0457``` Subject: Re: math equation Answered By: skermit-ga on 25 Feb 2005 14:55 PST Rated: ```First divide both sides by (1.012): (1 + F)^2 = 1.0457/1.012 Then take the square root of both sides: (1 + F) = sqrt(1.0457/1.012) Then subtract 1 to get F alone: F = sqrt(1.0457/1.012) - 1 Just for your convenience, I evaluated it already, and the answer is: 0.016513844105 Thank you for your question. skermit-ga```
 fizzleclizze-ga rated this answer:  ```0.016513844105 is only half the answer. When you take the square root of both sides, the +/- (plus or minus) sign needs to be added : (1 + F) = +/- sqrt(1.0457/1.012) therefore, F = 0.016513844105 or -2.016513844105 good luck with your studies!```
 ```Yup, forgot about that. Thanks jasonkoh-ga! skermit-ga```
