- The sum and product of Quadratic Equations:
What Is Quadratic Equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of f (x). The values of x satisfying the quadratic equation are the roots of the quadratic equation (α, β).
The quadratic equation will always have two roots. The nature of roots may be either real or imaginary.

From the number 2....how did (a-b) = (a-b)² ?
@@PromiseUkonne, he actually used that value to derive the formula. As u cant expand (a-b) without the square. And if theres no square , theres probably no other way to go about deriving it , do you get it
Thank you for the wonderful lesson video:)) Gon help in my exams tomorrow
You're most welcome. Best of luck 😊
definitely a better teacher and deserves more likes as well not like these other youtubers who do the barest minimum
Grateful for that 🙏
I like it man, u elucidate it very well
I'm glad you it was helpful
Wow, Just Wow. Their is so much Valuable Knowledge in this channel. Can't wait for more.
Thnak you for this, and may Almighty give u the capacity to keep creating this kinda valuable content. 🎉
This literally made it much easier for me to understand. Thank you so much
You're welcome. I'm glad it was helpful.
my school needs to fire all their math teachers- i literally learn better on youtube
I used to feel the exact same way at some point 🙃
😂😂😂
We will look into this
😂😂😂😂
Fr😭
Just tge first minute is very understanding , thanks a lot
May Jehovah bless you very well sit
Glad it was helpful!
Thank You do much bro, I've been trying to understand the reasons behind these formulas for 3 years now, anytime I try to memorize it, it won't be retained in my brain for more than a month
I'm really appreciate to this video because has helped me to understand this topic. Am having a question on the same topic, which says: Find the alpha and beta using quadratic equation and also the roots of x²-19x+25=0.
Please in your help!!!
Kindly send the clear question to my email address

Thank you sir for explaining in a simple way
You are most welcome
Thank you so much for this video! I had such a good time understanding

Thank you very much.
You are welcome!
I'm from india sir... It will help me a lot ... Thanks ❤
Very well explained, thanks sir
You are welcome
I didn't understand that number 2.
Where did that - 2alpha beta you wrote with blue pen came from?
It comes from the (i) there is alpha² + beta² = ( alpha + beta )² -2alpha beta
So sir put above value in the place of alpha²+beta² in (ii) part
I hope you understood... 👍🏻
By the way I think you are foreigners to me I'm from India 🇮🇳
Thank u sir it Gon to help me in the exam today
All the best. I'm glad it helped 😊
great video. do you have the answers (after you substitute in the number values from the quadratic equation)?
Yes we do
great! how do i access them?@@iqinitiative
Thank You!
You're welcome 😊
Thank youuu sirrr,now i'm understand 😊😊😊
Most welcome 😊
Nice lecture
Thanks and welcome
Fantabulous 💯

I hope I don't fail my maths exam, I am already on the verge of carry overs, I really do hate school and somehow this video makes it manageable
You can do it my guy 💪
Thank you very much sir
You're welcome
Can you break down how you expanded 4th equation cos it's confusing
I mean the 5th one
This can help 👇

Thanks gee 💪🏾💯🙏🏾
Any time
Question 5 im behind
Help
Real Number 5 is confusing why isn't there 2alphabeta at the beginning why is it just one?
THANK YOU!!!!
You're welcome!
Thank you for making this really easy for me and other ❤
You're welcome 😊
Infact this is the kind prove I want ❤
Glad it was helpful 😊
Can u please explain again
What of if we're not given the other questions how can you answer each independent
You derive each
I have a question 😢
@@PatriciaChisino-mj3ev Yes...
I just hope i don't fail my maths test is all
All the best on your test 👍
hye, can i get the answer of all the question ?
Sure
🎉❤
