So you used the condition \delta < (and equal to) 1
To obtain [tex]\left| x \right| < 1\ which means x is in distance of one.
So by putting x = 1 into (x+1)^3 you got 8.
Is this correct?

Not really. I was trying to show you how to think about it.
Now use the ideas in the other post to bound the factor
