please explain and show step to this factoring problem 9w - w3 and 3h2 the 2 power + 1+3a this really makes no sense to me HELP

Answer 1

you just need to d a lot of these problems. Look for common factors.

9w-w^3
clearly w can be factored out, so
w(9-w^2)
Now you have to recall the difference of squares is x^2-y^2 = (x-y)(x+y), so
w(3-w)(3+w)

As for the rest, I have no idea what

3h2 the 2 power + 1+3a

even means, much less how to factor it.
