There would be multiple maxes and mins for equations with a power greater than 2. There are questions about things like absolute maxes in more advanced classes. For algebra 1, we’ll stick to power of 2 only!
@@yourmathtutorvids When you rewrote -5 +- square root of 12825, you rewrote it as square root of 1285. Dropped the 2 from the tens place. At the end of the section you asked us to find the error. (2:39 bonus points!)
I found the mistake, your first factor was (-5 + 1282) divided by (-32) and when u brought down u forgot to write 2 after 8 ( u wrote it as -5+ (1285) divided by (-32)
Late reply to your comment but yes! you're right. this problem is actually to maximize revenue since we're not considering the expenses that are being used in the situation. awesome catch. too bad youtube doesn't allow edits after uploading!
Thanks for watching!
This was very useful especially since we are still studying quadratic equations in high school😁. Thanks a lot.
Love the way you gave realistic exam question examples! Great vid.
Seriously awesome video. Explained everything in a few minutes, more useful that hours of class at school .
Thank you! So glad this helped. All for learning things efficiently haha
Late to the party but this was wonderful help. Thank you
A big thanks…subscribed!
Thank you tahnk you thank you
Thanks for the video! Also, what are the formulas?
Wow you made it look so easy 💯🤝.That's was very well explained, plz another video, or is it okay to email you a question?
Late response - but feel free to ask the question here if it’s not too late!
Is the value of n ok? I mean the max poin
Was asked if the quadratic applied to equations where x has a power greater than 2. anyway, nice work. Oh, dropped the 2 when rewriting your sq root?

Where did i drop the 2? Trying to find it 😬

@@roginutah omg yes! I did drop the 2 there. I was replaying the video and could not figure out haha. Good eye!
you have messed up while entering equation into the calculator
If your frame of reference is at the top of the building, then the height h = -200 not 0. So t = 5.16 sec.
Can I ask is the answer to the first question correct?
I found the mistake, your first factor was (-5 + 1282) divided by (-32) and when u brought down u forgot to write 2 after 8 ( u wrote it as -5+ (1285) divided by (-32)
it was √12825. So it should be 113.24 and then calculate it.
how you go from 12825 to 1285 on the first one
I accidentally dropped the 2 :( it’s supposed to be 12825 not 1285
@@yourmathtutorvids So was your answer wrong or right in the end?
my exam is in 17 minutes lmaooo
Shouldn't the question in PT 3 be "how to maximize.revenue" instead of "how to max profit"? Higher revenue doesn't always equate to higher profit.

@@yourmathtutorvids I love the way you take corrections so positively🙂
Regina should not be tossing rocks off buildings, that is extremely dangerous.
Yes I agree
