Wrong formula

MyMathEducation commented on 08 Jun 2015

+Thelana Mejia sorry for the multiple comments...just trying to make sure this is clear.Factoring the difference in two perfect cubes which this video covers is completely different from solving cubes such as (x - 8)^3 which is really just multiplying (x - 8)(x - 8)(x - 8). When the cube is outside the parenthesis you are raising the entire binomial to that power and cannot distribute the exponent to the terms.

+Thelana Mejia the formula for factoring (a^3 - b^3) is:(a - b)(a^2 + ab + b^2) as used in this video.

+Thelana Mejia What do you believe is wrong with it?

Thank you for your useful video. I understood this video completely with 100% comprehension and I will now apply this Algebraic lesson into my Calculus I problem. Much appreciated and do more videos.

Your a term would be 25 and the b term is 125^3. The only problem lies in the fact that 25 is not a perfect cube.

Wait okay what if the second number in the equation isnt cubable even if theres a gcf

Thank you sooo much, I needed this to pass my final :D

Thank you so much for this explanation! Saved me.

Yes, there are a couple of different ways to square a binomial. Sorry, but no time to answer new questions, I just reply to follow up questions about the video.

Derek Jacobs commented on 20 Jan 2009

emm this is the longer term, both forms are correct i thing there are more than 2 forms to do it, anyways do you know if i have like (x/2 - 3/5) squared

Derek Jacobs commented on 21 Jan 2009

Mmm, It's quite simple what I was asking, never mind, I figured out by myself.
