factor x^3-27

OpenStudy (saifoo.khan):

@zaynahf to the rescue!!

OpenStudy (vortish):

lol saif

OpenStudy (anonymous):

Use the factoring of cubes formula: \[(a - b) ( a ^{2}+ab+b ^{2})\] And use the cube root of x^3 as a, and the cube root of 27 for b.

OpenStudy (vortish):

please do not use that formula it just makes it more confusing

OpenStudy (aripotta):

lol. but that's the formula

OpenStudy (aripotta):

what's the cube root of x^3?

OpenStudy (vortish):

but thoses formulas make it confusing unless i see them used in an example

OpenStudy (vortish):

x

OpenStudy (aripotta):

and what's the cube root of 27?

OpenStudy (vortish):

3

OpenStudy (aripotta):

so... (x - 3)(x^2 + 3x + 3^2) 3^2 = 9 so... (x - 3)(x^2 + 3x + 9)

OpenStudy (vortish):

that it ari

OpenStudy (aripotta):

yea i think so

OpenStudy (vortish):
