How to Simplify to get this answer? Fan + Medal

OpenStudy (anonymous):

\[(a^6-b^6) = (a-b)(a+b)(a^2-ab+b^2)\]

OpenStudy (anonymous):

can you show me the steps?

OpenStudy (anonymous):

@bibby please help

OpenStudy (somy):

first write as (a^3+b^3)(a^3-b^3)

OpenStudy (anonymous):

ok

OpenStudy (somy):

difference of cube formula

OpenStudy (anonymous):

idk that

OpenStudy (somy):

\[(a^3-b^3)=(a-b)(a^2+ab+b^2)\]

OpenStudy (anonymous):

ok

OpenStudy (somy):

\[a^3+b^3=(a^3-(-b)^3)=(a+b)(a^2-ab+(-b)^2)\]

OpenStudy (somy):

\[(a^3+b^3)(a^3-b^3)=(a+b)(a^2-ab+b^2)(a-b)(a^2+ab+b^2)\]

OpenStudy (anonymous):

Thank you

OpenStudy (somy):

yep u can simply some other stuff in there too like if you see heres (a+)(a-b) in there which gives us (a^2-b^2)
