There's a formula for solving problems like these. @jonask wrote that formula above.

So for example \[1000x^3  125y^3\to (10x)^3(5y)^3\] Using SOAP \[(10x5y)((10x)^2+(10x)(5y)+(5y)^2)\] and then you clean up thingsl like 10x5y=50xy and stuff like that

okay, the answer is 8(2x1)(4x^2+2x+1). I'm not sure how to get that...

Were you able to apply the SOAP method to your problem? could you convert \[64x^3\rightarrow ()^3\] ?

yea, I got 64x^38=(4x)^32^3=(4x2)(16x^2+8x+4). I don't know what to do from there

factor factor factor. 1) what # can you factor from (4x2) ? 2) what # can you factor from (16x^2+8x+4)?

err....I'm not totally sure...

I'll do the first one and you can do the second. (4x+2) = 2(2x+1) since you can divide 4 and 2 by 2:)

What is the larges integer number that divides 16, 8, and 4?

4, and then you multiply two and 4 and that's where the 8 comes from! I see!

Yay! Remember, next to perseverence (sp?), Factoring is probably the most important skill for math
