How do you use the binomial formula to expand #[x+(y+1)]^3#?
This binomial has the form
We expand the binomial by applying this property:
Where in given binomial
In the above expand we still have two binomials to expand
Substituting (2) and (3) in equation (1) we have:
We have to add the similar terms but in this polynomial we don't have similar terms , we can arrange the terms .
