How to find the discriminant and label the solutions of a quadratic

👉 Learn how to determine the discriminant of quadratic equations. A quadratic equation is an equation whose highest power on its variable(s) is 2. The discriminant of a quadratic equation is a formula which is used to determine the type of roots (solutions) the quadratic equation have.

The discriminant of a quadratic equation is given by d = b^2 - 4ac, where a is the coefficient of the quadratic term (x^2), b is the coefficient of the linear term (x) and c is the constant term. If the discriminant is a positive number, then the quadratic equation will have two real and distinct roots. If the discriminant is equal to 0, then the quadratic equation has two real and equal roots. If the discriminant is a negative number, then the quadratic equation will have two complex roots.

Note that the quadratic equation must be set equal to 0 before a, b, and c can be extracted. If the quadratic equation is not set equal to 0, then all the terms of the equation is taken to one side of the equality sign so that the other side of the equality sign will be 0.

I learned more in 2:33 than what my teacher taught me in the whole class

[caylencardenas]

omg you help so much you should be our algebra teacher

[jojom]

If only teachers would take the time and teach every detail like you do.Your such an amazing teacher.

[allysghoul]

You are literally the only reason im passing pre calculus 11 seriously bless this man

[ajaywarrior]

Amazing explanation
Hats off to your skill🙏

[SilverFoxRacing]

He is the reason why I understand algebra

[lavieniakharbudon]

Thank you so much tomorrow is my selection i really need this 🙏

[crystalangvil]

This was so helpful you have no idea I have finals and my teacher taught us about this method but I couldn’t understand. The wya you explain really catches my attention to learn thank you

[sujiithselvakumar]

How do u find out if the final number is rational or not?

[harshitawasthi]

I was doing a question of co ordinate geometry and had to use this in the question

[MariamAbdullah-nkhs]

Mr if u can do it more precise or more info please <3

[veronicaflores]

Me watching this last minute cus I have a test tomorrow

[JustJayYoutube]

What if the number is above 0. Like 56

[josephsyquia]

0:55 can I ask how did you get the 4ac? 😁

This is silly. What possible use are quadratic Equations. They dont predict rIain, wash windows, pay taxes or balance your check book.
