Question 1127627
 Tolu is 5years older than Daniel. Six years ago the product of their ages was 266. How many years from now will the product of their ages be 864 
------
Equations:
T = D + 5
(T-6)(D-6) = 266
----------------------------
Substitute to solve for T and D::
(D+5-6)(D-6) = 266
(D-1)(D-6) = 266
Solve::
D^2-7D+6 = 266
----
D^2-7D- 260 = 0
(D-20)(D+7) = 0
Positive solution::
D = 20 yrs 
So, Tolu is 25 yrs
------------------
Final Equation:
(20+x)(25+x) = 864
x^2 + 45x + 500 = 864
x^2 + 45x - 364 = 0
(x-7)(x+52) = 0
Answer:: 7 years
