Factor completely with respect to the integers.
I just need to see if I can simplify or factor the answers I got even further.
1. x^3 + 64
Answer: (x+4)(x^24x+16)
Can this simplify any?

Answer 8(x2)(x^2+2x+4)
3. x^2x^2+4x8
Answer: (x^2+4)(x2)
4. 2x^3 + 3x^2  32x  48
Answer: (x^216)(2x+3)
5. 6x^318x^22x+6
Answer: (6x^22)(x3)
6. x^4 + 12x^3 + 4x^2 + 48x
Answer:(x^3+4x)(x+12)
They look good to me. The first cannot be simplified.
