Okay, is this factoring right?

OpenStudy (anonymous):

\[64-z ^{6}\] \[(8^{2})-(z ^{4})^{6}\]

mathslover (mathslover):

\[\huge{a^2-b^2=(a+b)(a-b)}\] \[\huge{\text{Use this identity}}\]

mathslover (mathslover):

\[\huge{8^2-(z^3)^2}\]

OpenStudy (precal):

4 times 6 does not equal 6

OpenStudy (anonymous):

Oh, still getting the hang of this..

OpenStudy (precal):

mathslover is correct

mathslover (mathslover):

\[\Huge{(8-z^3)(8+z^3)}\] \[\Huge{(2^3-z^3)(2^3+z^3)}\]

mathslover (mathslover):

we made 8 as 2^3

mathslover (mathslover):

now we will apply \(\huge{a^3-b^3=(a-b)(a^2+ab+b^2)}\)

mathslover (mathslover):

and \(\huge{a^3+b^3=(a-b)(a^2+ab+b^2)}\)

mathslover (mathslover):

got it?

OpenStudy (precal):

I did, I think the asker left
