4 more years until you graduate high school
Today is 2016
2016 + 4 = 2020
The year will be 2020 when you graduate high school.
Integers are 2n and 2n +2
2n * (2n + 2) = 840
4n^2 + 4n -840 = 0
Solving by quadratic formula:
n = 14 and n+2 = 16
Therefore the integers (2*n and 2*n+2) are
28 and 30
check:
28 * 30 = 840
