As its Quadratic equation I solved it using root method

I appreciate the medals and all , but I'm not sure if it's the right answer you're looking for. 

I know if you take the year x^2 and subtract his age, you'll get his date of birth. Then given the time he died, you can just do the math.

It's like, if I'm 15 and the year is 2011, then I subtract 2011 - 15 and my date of birth = 1996. Then if I died in 2012, then I died when I was 16.

x^2-x=18(something, probably)
42^2=1740
43^2=1849 (seems likely) makes him 32 years old (possibly 31, if he died earlier in the year than he was born)
