I will restart but not complete this:
The question number was from this: http://www.algebra.com/algebra/homework/quadratic/Quadratic_Equations.faq.question.971204.html

A man is x^2 age while his son is x years of age.
In 4x years, the man will be twice as old as his son.

m and s for MAN and SON, their present ages.

;

Substitute for m and s in the "4x" equation.

which is an unsimplified quadratic equation in just the one variable, x.

This can be simplified, put into general form, and then solved for x.
