Here is my question. It's from a pre-calc class, but feels more appropriate here in the algebra section.
Factor the expression completely.
5 * (x^2+4)^4 * (2x) * (x-2)^4 + (x^2+4)^5 * 4 * (x-2)^3
The answer in the back of the book is:
2 * (x^2+4)^4 * (x-2)^3 * (7x^2-10x+8)
I'm aware of special factoring forms. I could do all the math for (x+y)^4 etc, etc, but it gets really long . I was wondering if there was a more elegant solution. After scouring my book for any clues with no luck I feel really lost! Any help would be greatly appreciated!
