Question 942051
If the product of two consecutive positive even integers is equal to 168,
 then what are the integers?
:
let two consecutive even integers be: x, (x+2)
:
the product = 168
x(x+2) = 168
:
distribute, subtract 168 from both sides
x^2 + 2x - 168 = 0
Factors to
(x+14)(x-12) = 0
The positive solution
x = 12 is the 1st integer, then 14 is the second

Check 12 * 14 = 168
