A man is currently 20 years older than his oldest son. His oldest son is currently two years older than his youngest son three years from the current time, the product of the ages of his sons will be 10 more than 11 times the age of the father. What is the current age of the man's youngest son?

Thank you for the opportunity to help you with your question!

Let oldest son be X

Man is X+20

youngest son X-2

Three years from now,therefore;

(x+3)(x+1)=11(x+20)+10

x^2-7x-227=0

then solve using quadratic formula

we get x=19 or  x=-12

Youngest son=19-2

        =17years


Please let me know if you need any clarification. I'm always happy to answer your questions.
