- This lesson will demonstrate how to solve factorable polynomial inequalities using algebraic methods. Quadratic, cubic and quartic polynomial inequalities will be included in the examples.
I FINALLY UNDERSTAND THE PURPOSE OF THE TABLE AFTER WATCHING SOOO MANY VIDEOS! THANK YOU SO MUCH!
u lied im still dumb
hands down best explanation and plus i loved all this editing you put in the video thank you lots!!
Thank you so much AlRichards314 my mom was going to take away the ps2 if i didnt figure these out...
Very helpful. Thanks!
In what book can i find this table?
THANKYOU SO MUCH FOR THIS
THANK YOU!
Excellent lesson
Hey, thanks.
Can you explain why you do certain things? LIke this example was fine but I don't know why you did some steps so how do I solve different test problems?
You need to be lots more specific if I'm going to be able to reply in a way that helps you.
Never mind. The only thing I was confused about was where you got the numbers for the synthetic division from. I didn't know how to pull the p/q from an equation. I re-watched the video and I understand now. Thanks :)
You're welcome. Have a good day.
Great technology for this! Great explanations! At 8:40 you introduced wrong inequality sign.
Actually, you don't need the full ≤ symbol there are 8:40. The reason being is that we are only considering the sign within all the intervals. At the interval boundaries (-3, -2 & 1) the value of the expression is 0 which has no sign. Thanks for the comment anyway. I could have used < or ≤ there.
@@AlRichards314 Just friendly discussion. It wasn't consistent with your other problems (especially the last). You are rewriting the actual inequality. You were not dealing with signs at that point in the process.

So many ads... I am fed up of them.
