Question 29197
i assume you mean all possible INTEGER values of b? If not, then there are an infinite number of answers...


For just integers:
1*12
2*6
3*4


are pairs that multiply to give 12. Since both bx and 12 are both +ve, then the factors are both +ve too, so the middle term will be one of the following:
1*12 --> 13
2*6 --> 8
3*4 --> 7


So b is either 13 or 8 or 7
