Our guest answer is good but I will certainly just present you just how to carry out it formally,

Let the very first number it is in x

and the next even number will certainly be x+2

x(x+2)=168

x^2+2x-168=0

I want 2 numbers the multiply come -168 and include to 2

Since they multiply to a negative, one needs to be neg and also one pos

Since they include to a pos the "biggest" one is positive

factor(168) = (2^3*3)*7

168=2*2*2*3*7 = (2*2*3)*(2*7) = 12*14

so the numbers space 14 and -12

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

x=-14 or 12

so the integers space -14 and also -12

or

12 and also 14

just like our guest already said. :)
