let x = # hours it takes B alone
then x+2 = # hours it takes A alone

1/x = fraction of job B does alone in 1 hour
1/(x+2) = fraction of job A does alone in 1 hour

Together the two do the job in 8 hours, so the fraction they do together in 1 hour is 1/8:

Multiply by the common denominator, :

Solve using the quadratic formula or a graphing calculator (or any other method you might know)....
