Question : 2x^7-32x^3

When I factored it I got:

2x^3(x^2+4)(x+2)(x-2)

The book answer is:

2x^3(x+2)(x-2)(x^2+4)

Does it matter what order I put these(x+2)(x-2)(x^2+4)in?

If it does matter can you please explain why it goes in the order it does!

Thanks,

Miley :)

Answer 1

Your answer and the book's answer are really the same. It makes no difference in what order you write the factors.

a x b = b x a. OK?

Thanks for the compliment. :-)
