Answer:

12 & 14

Explanation:

the work: x = first even number, (x+2) = second even number

The equation


x(x+2)=168


x^(2) +2x=168


x^(2) +2x-168=0

Factoring


(x-12)(x+14)=0

first factor


x-12=0\\x=12

Second factor


x+14=0\\x=-14

The solution is the positive number

x = 12 is the first even number

x + 2 = 12 + 2 = 14 is the second even number

Hope this helps
