Question 1135678
let x equal the number of years.


(60 + x) * (25 + x) = 2244


simplify to get 1500 + 60x + 25x + x^2 = 2244
combin like terms and reorder in descending order of degree to get:
x^2 + 85x + 1500 = 2244
subtract 2244 from both sides to get:
x^2 + 85x - 744 = 0
factor this quadratic equation to get:
(x - 8) * (x + 93) = 0
solve for x to get:
x = 8 or x = -93
x can't be negative, so solution is probably x = 8.


(60 + 8) * (25 + 8) = 68 * 33 = 2244.


8 years is your solution.
