(New Version Available) Compound Inequalities

[@jessemeyer1157]

Aside from the mistake on number 2. This video answered all my questions that others did not. So many tutorials fail to explain clearly the simple reasons why you get 'no solution, 'all real numbers', and the difference between AND and OR. Thank you for this. It may seem obvious to some, but for those who have questions you'd be surprised to see the lack of explanation.

I often find this teacher's videos more useful than Khan's. or good to watch both. Thanks much!!!

[@Mathispower4u]

Thank you. I hope you will share with your classmates.

8:47, the parentheses should be a bracket before the 3 in the second example Also, in the same example, it starts with the fraction of -5/2, but then he turns it into 2.5, but it should be -2.5

[@kissmefourtimes]

that's what i thought!!!! #readthecomments lol

[@rickyljordan]

I believe there is another error at 8:30. The interval notation should be (-INF ,-2.5) [3,INF )

[@Mathispower4u]

Yes, I will work on recording this video again.

[@rickyljordan]

I realized I had missed the (-) on the 2.5 so I edited my comment but all else was good. Thank you for these videos. I have learned a lot of new techniques.

[@Mathispower4u]

I'll have an updated version tomorrow. Thank you for the notification.

There's a mistake in example 2, 2.5 is supposed to be -2.5, and (-inf,-2.5)U[3,inf)

[@alicevanness6612]

I think there's a mistake on example solving inequalities #2 2x+3 < -2 -5/2 = -2.5 ?

[@mattc2958]

You could also say -2 1/2

[@Mathispower4u]

Yes, you are correct. Sorry for the inconvenience. Here is a new version. kzbin.info/www/bejne/i2OTdaNqobWJpdE

[@HedgeKnight-m8w]

This is better than khan academy

[@bsinghvi2]

In your videos, can you also include Set-builder Notation? That would be very helpful! You are a great teacher! Thanks!

[@gsgambe01]

did i miss something how is -5/2 = 2.5 isn't it -2.5?

[@Mathispower4u]

Yes, you are correct. Sorry for the inconvenience. Here is a new version. kzbin.info/www/bejne/i2OTdaNqobWJpdE

[@minaboutros5408]

there is a mistake in the example 2x+3=2. First answer should be x

[@Mathispower4u]

I made a new version 4 years ago. kzbin.info/www/bejne/i2OTdaNqobWJpdE thank you

[@mephatboi]

fantastic, as usual

[@meenashirazi5319]
