Completely factor 27x3 - 512y3
Completely factor 4x2-9y2
I am having issues with these certain problems. Please explain if possible how to do this. I want to figure it out but it's not on any of my lessons that the teacher has released.
For the first one:
If you want "Binomial factoring"
Then there is no common factor for 27 and 512
Thus factoring it by a common factor isn't possible.
There is a formula for this:
We will use the second one as it is similar to your question "Difference between the two cubics"
Difference between squares.
hope that helped, you really need to memorize the formula and have practice!
