The discriminant of a quadratic equation
Переглядів 1592 місяці тому
This tutorial video explains by using examples the nature of the roots/solutions of a quadratic equation. b^2-4ac less than zero (real different roots), b^2-4ac equal to zero (equal roots), b^2-4ac greater than zero (imaginary / no real roots). Also referred to as the Discriminant. Leaving Cert Algebra Maths

Can u do 2024 and 2022 plz
Why not use the quick method? ua-cam.com/video/WsK6CE4GjDw/v-deo.html
thank you king
Would be nice if you put the co geometry into a playlist
thankyou so much for this video
Method name?
expanding brackets and finding like terms
Hie may you please do a video on how to use the abs function on the casio fx-GT CW
um sir idk if i am right but in example four x < -2 is a solution right?
im actually 9th grade im trying inequalities and i tried this sum and got x < -2 is also a solution .
oh nevermind sir i substituted the value in the eqn and it gave me 1 > 2 . i cleared my doubt thank you
How do i get frequency on fx 991 cw it looks similar
Super helpful
Glad it helped! Thanks for the feedback
👍
So many steps not needed. X has it's own button! Also tools and table range saves typing them in including faffing with the negative
Thanks
you're welcome
Cheers I have my mocks coming up now I know how to do it on my calculator
You're welcome. Best of luck in the mocks.
very helpful only problem was you were yaping too much
I am cooked..
Thank you very much❤
No problem - glad to help
When i put the whole thing in my calculator it gave me minus one on the plus
why is there no sd button on this calculator thats so time consuming :(
Yes its a shame. It takes getting used to
you don’t even have to press anything by doing this!! settings > calc settings > input/output > mathI/decimal0
Thank you!!
wow thank you so much 🙏
You are very welcome
👍👍👍
Great videos, Helped me to understand 5yat modulus can be replaced by squaring it .... And solve it as quadratic inequalities.... Thanks alot ❣️
glad it helped.
Why do i feels like it would work too by doing base x height x pie😅
Good method. But much much longer than it needs to be.
shouldn't it be -36? I^2 = - 1
Remember a modulus of a coordinate is the distance from the origin. So it is 8 units along the real axis and 6 along the imaginary axis. So it forms a 8 6 right angle triangle and you use Pythagoras normally. Don't overthink it with it being complex, just square the coefficients
Is it 6 grade math?
I feel assulted by how you wirte the letter X
That's how your meant too write it
You have to do it like that to determine if it's a multiplication symbol or the x variable.
thank you for this video, i'm going through exam papers for my jr cert in 2025 and this will help me loads. Kudos!
thats great. On our youtube channel we have other year solutions as well as mock paper solutions
Are you able to switch between radians and degrees without deleting your previous sum?
I know how to do all the steps but whats the purpose of changing the signs , would there be a case where u don’t change the signs?
we change the sign because we want to take the bottom line away from the top line. So that the terms cancel out. You will always change the signs (take away) when doing long division. Hope that clarifies for you.
Thank you
hope you found it helpful
Is this HL or OL?
Hi there. HL junior cycle. OL and HL leaving cert. Hope this clarifies
@@tullamathsso this kind of question could be asked in all levels basically?
@@geoffcorc88 correct. except for Junior Cycle Ordinary Level
Was so helpful❤
thats great!
Hello sir you should put a zero at the end of the numbers because they're money thats what my teacher told me
thank you 🙏🙏
Thank you - I hope it helped
Tyy this was soo helpful
Thats great - thanks for the feedback
You don’t need 2 variables though do you? It’s 1 variable…
ty bro
I'm glad you found it helpful
Thank you 🙏🏾
You are very welcome
This did not help at all
thanks
Glad it helped !
At 1:37:42 how come you use 4.03 instead of 0.89
0.89 is only the reference angle. COS is negative in quadrant 3, hence the full angle is 4.03.
Maths my no1 opp
Help me this math (y_3=square root y+9)
thank you!!! it’s very helpful to me!
You are very welcome
Youre a lifesaver bro
glad to of helped!!
If u plug zero in as x it will be an invalid quotient proving you are wrong to say anything number is 1. You have to say that zero is the exception
