You can put this solution on YOUR website!
k+%283x+%2B+3%29%28x+-1%29+=+0 and x+%3C+1
We have a product that is equal to zero. By the Zero Product property we know that is a product is zero, one or more of the factors must be zero. With a little thought we can determine that both 3x+3 and x-1 are always going to be positive if x+%3E+1. So that leaves k as the only factor that can be zero. So it must be zero!
