Question

Simplify (a^6 - b^6) ÷ (a^3-a^3) ÷ (a^2-ab+b^2)

Can anyone help me with this? I've spent a long time on this question and I can't figure it out. Tried it on wolfram alpha as well but it doesn't give me anything

thx

Answer 1

`(a^6 - b^6) / (a^3-b^3) / (a^2-ab+b^2)`


`=((a^3)^2 - (b^3)^2) / (a^3 - b^3) /(a^2-ab+b^2)`


`=((a^3 + b^3) (a^3 - b^3))/((a^3 - b^3)) / (a^2-ab+b^2)`


`=(a^3 + b^3) / (a^2-ab+b^2)`


`=(a^3 + b^3)/(a^2-ab+b^2)`
