Question

how do you factor 1-8a^6?

Answer 1

here's a hint. the formula for difference of two cubes is \[\huge a^3 - b^3 \implies (a-b)(a^2 + ab + b^2)\]
does that help? or do you need more help?

Answer 2

ya i still dont understand- it says that in my book but i dont understand it.

Answer 3

here's another hint \[\huge 1 \implies 1^3\]
\[\huge 8a^6 \implies (2a^2)^3\]
do you get what i'm implying?

Answer 4

alright thanks so you just find the cubed root of the numbers which represent to a and b and just plug it into the equation right?

Answer 5

right
