I am currently teaching myself some maths but I have found these two questions on the internet, and I'm completely stuck.
The questions are:
1.A man whose birthday was January 1st died on Feb 9th 1992. He was years of age in the year for some interger . In what year was he born?
2. If and are both prime numbers, find, with justification, all possible values of .
I think that question 1 is to do with quadratics and you can tell that if is , then would be which looks to be the most sensible, although I do not know where to go. Question 2 I don't really know where to start.
These are both really nagging me and I cannot get the answers.
Thanks so much for any help given!
