Hint: Add 'x' years to both ages to get and years. Multiply them and set them equal to 208 to get . From here, FOIL out the left side and subtract 208 from both sides to get everything to one side. After combining like terms and simplifying, use the quadratic formula to solve for 'x' (note: ignore any negative solutions)
