Note that and the property of powers:
So:
In the difference of squares it can come in the form of where n is an even number. The factorization is
However in the following problem I am lost at a particular step. Namely, how turns into
If someone could walk me through this it would be greatly appreciated,
Many Thanks
so irrespective of the fact the book did not factor completely would be correct? If so how do you arrive at that particular answer
Also could someone walk me through this problem as well
Lost in this one as well unfortunately . I understand breaking down but how that yields I am not certain.
This is a handy site for understanding the factoring of the difference of two squares and also has links for the sum and difference of cubes as well:
