Evaluating some symmetrical of quadratic roots
Vložit
- čas přidán 16. 08. 2024
- The symmetric property of quadratic roots states that if a quadratic equation has roots α and β, then the sum of the roots (α + β) is equal to the negative coefficient of the linear term (b) divided by the coefficient of the quadratic term (a), and the product of the roots (α * β) is equal to the constant term (c) divided by the coefficient of the quadratic term (a).
In mathematical terms:
1. α + β = -b/a
2. α * β = c/a
This symmetry between the roots of a quadratic equation is a fundamental property and is often used to find the roots when the coefficients of the quadratic equation are known.
Omg your voice is so soothing, I could listen to you solve math equations for hours!
Thank you sir. Reminds me a lot of 100L math 103, if I could remember the course code.
I wish students in their oLevel and A Level will give attention to your channel.
May Allah give you more strength to continue the good work
Ameen 🙏
Please sis substitute for for better by ur self
And now I can finish writing my assignment which is due this Friday.😭 You're a lifesaver sir. I'm glad I came across your channel.🙏🏾
for option b (a²+b²), 29/4÷25/4 can also be expressed as 29-25/4 which is 4/4 =1
I love your teaching
Thank you 🙏
nice video, please can i ask whats the name of the app you use for your teaching. the whiteboard app
Samsung note
Thanks
Wonder
🙏
