Master Mulitplying Rational Expressions

[@PotassiumNeon]

I kept on answering my teacher’s questions about this. She got shocked. And asked me, “do you have another math teacher? Do you tutor?” And I answered. “Yes.” She backfired with “who?” Me: Sir. Brian McLogan

[@colinbaker743]

Mr. McLogan, You are such a great teacher, If I had you for math I would have like a 95 for the year, guarantee it.

[@benlee5039]

More like 100

[@calebheller7]

For your 3rd example your first trinomial in the numerator is not (x+4)(x+3) it should be (x-1)(x+4)

[@brianmclogan]

great catch! thank you for noticing and letting me know

[@wolf3276]

for his 2nd example could he cross off both the x's and have it be 4/2(-5) at the end or does it not work that way

[@colinbaker743]

@@wolf3276 No you can't do that because it is a combined number rather than two seperate things

[@wolf3276]

This is so helpful Mr. McLogan. Thanks for sharing your notes!

[@benlee5039]

How come youtube teachers are better than my real teachers. I should tell them to show your videos on the smart board. Saves them time and us time!

[@tracykistemaker2290]

thanks for the help you put more life into your teaching which helps me learn instead of my teachers boring lectures

u teach me more than my teacher does

Thankyou very much I’m very confused on how to learn how to multiply rational expressions but when I watch this video I understand it

[@dreamyskieye]

ugh i have a test on this for tomorrow i'm freaking out, u explain better then all the teachers i had

A LIFESAVER! A TRUEMASTER! TAHNK YOU Mr. McLogan

[@boccaluppo930]

On the third example shouldn't it be 2x(x+2)?

[@mevissah]

If ur talking about the first numerator in example 3 it’s supposed to be (x-1)(x+4)

[@horizonbrave1533]

So would you recommend ALWAYS factoring prior to multiplying fractions?

[@brianmclogan]

yes!!!!!!!!!

[@dalefausto3383]

You should be my math teacher

This video was so helpful! you deserve more views! :)

thank you! glad it helped!

You da 🐐

[@karlmariusfurog9469]

why in the term 4x-16 becomes 4(x-4) why the 4 still same

[@brianmclogan]

because if you multiply the 4 back you get the original expression

[@karlmariusfurog9469]

+Brian McLogan ty it help

[@janetxoxo452]

example 3 is off, it has to be (x+4)(x-1). at first i thought i was wrong but i tried it with the +3 and it obviously didn't work but this video is still very helpful !

[@jeffreyzamora6337]

On the third example I think there is something went wrong. Or you miss

[@TheConqueror009]

Your third example is wrong.
