Factor completely x^3 + 64 z^3+1 t^3-1000 27x^3+1 64-125x^3 x^3+2 5x^3-40z^3 x^3+0.001 z^6-1 x^12-y^3z^12

OpenStudy (anonymous):

thats alot

OpenStudy (anonymous):

ahah i know, im just checking my answers for thee ones im unsure of.

OpenStudy (anonymous):

(x+8)^3 (z+1)^3 (t-10)^3 (3x+1)^3 (8-5x)^3

OpenStudy (anonymous):

I think thee first one is (x+4)^3

OpenStudy (anonymous):

oh yea sorry bout tht... yea i was just checkin if yu were aake.. yea i was...

OpenStudy (anonymous):

i also dont think that the 4th one is correct.

OpenStudy (anonymous):

3*3*3

OpenStudy (anonymous):

nor thee last one....

OpenStudy (anonymous):

4 instead of 8 sorry again

OpenStudy (anonymous):

yeah when i factor it out i get 27x^3+27x^2+9x+1

OpenStudy (anonymous):

yu sure?

OpenStudy (anonymous):

yeah i did it like 3 times.

OpenStudy (anonymous):

(3x+1)(3x+1) is?

OpenStudy (anonymous):

9x^2 +6x+1

OpenStudy (anonymous):

times another 3x+1... oh yea wen you do do tht it does come out to tht but tht shorter on is supposed to be the simplier form

OpenStudy (anonymous):

but it doesnt equal 27x^3+1

OpenStudy (anonymous):

yes it does just a different form

OpenStudy (anonymous):

thee last one either, it comes out to be like -125^3+300x^2-88x+64

OpenStudy (anonymous):

again ith those 4 yea i need to brush up on them

OpenStudy (anonymous):

can you help with the last 5..

OpenStudy (anonymous):

uhh hold on for about 7 mins. dinner.

OpenStudy (anonymous):

lol okay, thanks! :D

OpenStudy (anonymous):

and im back.

OpenStudy (anonymous):

wooo! okay.

OpenStudy (anonymous):

x^3+2 is already factored 5(x+2z)^3 (x+1)^3 (z-1)^3(z+1)^3 (x^4-yz^4)^4

OpenStudy (anonymous):

OMG! Thanks!
