Thread: Finding two numbers from one (easy)

Hello.

I have the following problem: I have a number I obtained through a formula using two numbers. My goal is to find the two original numbers having only the result of the formula.

I have the formula and the following inequality:

x = ((a+9)*(a-2))/2 + b

a > b

Is there some way to find a and b only having the value of x and knowing that inequality is always valid?

ps: I know the max values for a and b

Thanks.
