You can put this solution on YOUR website!
If one of the zeros of y=x%5E3%2Bbx%2B1 is 1, this means that if you plug in x=1, then y will be zero. In other words, you'll have the equation 0=%281%29%5E3%2Bb%281%29%2B1. From here, you have a simple linear equation in which you can solve for 'b'. I'll let you do that.
