Solving Quadratic Equations by Taking Square Roots
มุมมอง 5619 ปีที่แล้ว
This video demonstrates how to solve quadratic equations using the "square root" method. The initial part of the instruction is dedicated to recognizing the type of quadratic equation that is a legitimate candidate for the technique.
Thank you Jeff. I have an exam tomorrow too.
Feels weird, man
Jeff wyaaaaa
Thanks for a solid, simple tutorial!
I wanted to solve 8A^2 + 6A + 5 I got: -3[Plus or Minus] i times the Square Root of 31 ALL divided by 8 Then, on my TI-83 Plus, I typed in: (-3+i(31))/8 This gave me the answer: -375+.69597054..." I have never seen the plus sign in the answer. What does that mean?
algebra one final time guys loo
Thank you!
when i type my equation in i cant zoom out
how 80'000 people watched this video and only 300 liked is mystery to me, everyone that clicked on this video got the answer they were looking for. Thanks for the help!
There should be a class on using these pieces of sh*t before pre calc lmao
I fucking hate algebra
agree
why am I getting a different answer and I followed step by step? I can't fail my final
How'd it go
@@Josh-je2ni I want to know too
Sir, you just saved my entire math grade
Thanks for making it simple and not trying to cover too much information.
here from an online class 😔
She did my bich like stephen curry
Sike nigga this was awesome sauce🔥🔥👌🏿
thank you for this!
why is it so damn hard to make a video where you push the buttons on the calculator and show us how to find x? Is no one on youtube competent enough to make helpful video on this topic?
xEJDx- ikr
I know this is late but you click X,T,O,n under "LINK". One down of the "2ND" button and one to the right of the "ALPHA". Sorry for the late response but hope all is well and have a good one.
this did not help . im gonna fail .
Really late, but you could just use the quadratic formula instead
@@bryce7289 even more late but if he doesn’t know how to graph a quadratic. He prolly doesn’t know how to use the quadratic formula
@@jeremysaluta5757 Even more more late, you bring up a good point on this dude's skills. I mean you're just putting numbers in a calculator. It's pretty simple.
@@bryce7289 Even more late, but he could factor it out
It just says no sign change
your equation did not have a solution
Good video
🙏🏾God bless you
I want to die....
somz saltz i want peen
U r DULL!
Cool
the calculator is so old that it doesnt help.
how do you know where to put the bounds
Candy Cane Yeah Ikr, that's what I was like lol
lemonade so beyable you put the left bound on the left side of the point at which the parabola crosses the x-axis. Then the right bound is placed on the right side of the intersection of the x-axis. If you are finding the intersection on the left, do NOT cross the axis of symmetry when placing the right bound on the right side (which is below) the intersection. Place the left bound anywhere above the left intersection. For the right intersection, do NOT cross the axis of symmetry when placing the left bound. It is the same as finding the left intersection but the left bound is placed below the intersection and the right bound is placed above. What you are doing is marking which intersection you want your calculator to give you the coordinates of. They are boundaries and there should only be one intersection on the x-axis inside these boundaries. This is why you place two different sets of boundaries.
lemonade so beyable i dont know if youre passed learning this but i still want to say sorry if i was confusing
@@sxpremesushiihe sorry for the late response so to find the second answer you just click enter & don’t move anything?
zeroes of a quadratic
jeff how is it man
I wrote myself a program to do that
do ypu have a youtube program for it
Jackson Anderson what do you mean?
