Question 923975
Currently:


Peter: 7 years old
Mary: 3 years old


-------------------------------------------------------


x years into the future


Peter: 7+x years old
Mary: 3+x years old



-------------------------------------------------------


Multiply their future ages and you force that product to be 96


(7+x)*(3+x) = 96


21 + 7x + 3x + x^2 = 96


x^2 + 10x - 75 = 0


I'll let you take over.

Let me know if that helps or not. Thanks.
