i cant cube root 3

snowflake0531:

First, writing it out \[192x^3 -3\] you are correct, you can't cube root 3, but you can divide 192 and -3 by 3 Can you first factor out 3?

snowflake0531:

Divide both terms by 3

Aqual:

ok

Aqual:

64 and 1

Aqual:

or, -1 i should say

snowflake0531:

Yep so \[3(64x^3 - 1)\] Agreed?

snowflake0531:

And now that you have this, put the 3 to the side, and just do the stuff in the parenthesis

Aqual:

ohhh

Aqual:

ok
