Professor RobBob, thank you for another great video/lecture on Factoring Polynomials Differences of Squares. In Mathematics pattern recognition is a method that student should use to solve all types of problems in Math and Science. There is always a pattern in Factoring, whether its by difference of squares, by grouping or trial and error.

BAM! I really like the videos. It is nice to have a quick refresher after lecture to come home to. This is making homework much easier! Thanks!!!

+john burens 3 weeks and still watching...BAM!!! Always glad to hear when students find them so helpful and take full advantage of all the free help that is available. Thanks for choosing my channel to learn from and sub to and please take the time to share this channel with others as you remind them to like and sub to help these free educational channels keep growing and remain free:D

Thanks a lot! :D Finally understand how this concept works!! My Algebra class has this down and I was struggling to figure all of the practice problems my teacher was giving me and now I understand! Thank you 😁

+United Skylanders America you're welcome, glad it helped. Please take the time to like, sub and share my channel with the rest of your classmates and tell them to please do the same...you might even share with your teacher as an additional study reference for their other students...BAM!!!

Good job! This is clear and concise.

This really helped. Thank you Mr. Ttarrou!

Thank you for watching my math lesson. I am glad you found it helpful. Please help spread the word about my math channel!

you explain better than my teacher! at the class, i just keep on yawning, really! sleepiness strikes! i don't understand what she's talking about....so i always end up with zero in my quizzes..which makes me feel so bad..i then concluded that i maybe dull when it comes to mathematics...

A couple of very awesome students just gave me this shirt as a goodbye gift...they are graduating:) Thank you very much!!!

Amazing....I understand!!! Thank you!!!

i love you very much sir!!! your a big help, we have examination tomorrow and i do understand your explanation...thank you!!!

love the t-shirt!

You're welcome. Get a group of friends together, you can all watch my videos together and it will be just like I'm your teacher:) Keep watching and sharing with your friends and classmates:D

thank you for your help. I have a question: for the last problem my result is different I got 4xy instead of - 4xy .can you help?(x-y)^2 - (x+y)^2[(x+y)+(x-y)] [(x+y)-(x-y)](x+y+x-y) (x+y-x+y)(2x) (2y)4xy

+dawdi stati You are putting the (x+y) first instead of second. You are factoring (x+y)^2-(x-y)^2. When you change the order of subtraction you get opposite answers like 5-2 is 3 where 2-5 is -3. Thank you for watching:D

thanks gangsta

at 5:09 what if i have a third term what would it be? c?

@profrobbob

If you have a third term you would not be factoring a binomial which is what this lesson is about. You would be factoring a trinomial so this is not the lesson you want to be watching. Judging from the example you pointed out, I am guessing your third term is an xy term, and if that is the case it would be the middle term.

It is a pattern that only works for multiplying binomials.

On the 2nd problem aren't you able to pull out a GCF?

@profrobbob

10 жыл бұрын

Yes you are, and when there is a GCF you should factor it out first. I should have made that example with coefficients of 4 and 25, or I could have factored out a 4 first. Thank you for your question and watching.

Kind of an odd question, but why do we not distribute the exponents in the last example?

@profrobbob

10 жыл бұрын

Do you mean in (x-y)^2 ? Because there is more than one term in the parenthesis you cannot distribute the power of two with the power rule. When you square a binomial the answer has 3 terms.

ProfRobBob Ah ok, so you can't distribute when there is more than 1 term in parenthesis?

Why don't you use the "FOIL" term?
