Question

Algebra help! Factor x^5+32

Answer 1

32 =2^5

ok ?

Answer 2

hope this will help you

Answer 3

I understand that but I still dont know how to factor it

Answer 4

there are x^5 +2^5 so how can you factoring these ?

Answer 5

factorizing

sorry

Answer 6

do you have any idea ?

Answer 7

x^5 =x^2 *x^3

yes ?

Answer 8

ok

Answer 9

would you factor is like a sum of squares and a sum of cubes?

Answer 10

yes right think about !!!

Answer 11

(x^2+4)(x+2)(x^2-2x+4) is this right?

Answer 12

so i think you can check it too the same like me ,yes ?

Answer 13

how?

Answer 14

(x^3 +2x^2 +4x +8)(x^2 -2x +4)=
=x^5 -2x^4 +4x^3 +2x^4 -4x^3 +8x^2 +4x^3 -8x^2 +16x +8x^2 -16x +32=
=x^5 +4x^3 +8x^2 +32

so than result that not is right

Answer 15

you have missed some factors there

Answer 16

maybe we can use factor's theorema, to factorizing it
because x=-2 is one of the root of x^5+32, so (x+2) is one of factor of x^5+32. just do synthetic division it will work

Answer 17

can someone show me how? I dont know what factors theorema is or what synthetic division is.
