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

👉 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 honestly wish I had a teacher like you, one that actually explains the problems. My teacher just wrote out a problem on the board and without saying anything just went through the steps and expected us to learn it, no I am struggling so hard in math and geometry that it's not even funny.

[brokeandstoked]

This guy has taught me more than my math teacher lmao

[sharanyaaaaa]

I had maths exam today and I haven't yet touched the book... thanks dude

Online school sucks. I was learning for the first time this year in class and then corona happens.

[crimsonkyrptonite-roblox]

My teacher teaches problem in school..
this man: im bout to end this teacher's whole career.

You don't understand how much you've saved my life. The notes i got were confusing, along with getting the equation to 0. I was taught incorrectly. It's much easier the way you've explained it. Thank You.

this dude helping me keep my grades up through quartine, its hard when im not face to face with a teacher

[mystick]

I’m subscribing .. this helped a lot thanks 🙏🏾

[acemyrickjameslloren]

Oh man
This guy is taught me everything
Now I've seen everything 😅

[Stephanie-rfru]

he's the only reason I'm passing my math 2 class. I wish I found him years ago tho these videos woulda rly helped me in middle school

[martaeronsantiago]

That is the right style of teaching solutions for me.
Thank you!

0:01-0:04 Rip headphone users. (with very sensitive hearing, that is)

[imslickzz]

This isnt how my teacher taught me discriminant
My prof. aint good

[SimReaper]

just got this way better than when I was in school :)

[Sena-pu]

You explain things 10x better than my math teacher

[mesunflowrme]

Thank you so much so making these videos 🙏 I love math but my teacher this year makes things very confusing and these help me a lot

[elijah]

how will you know if it's two or one rational or no rational?

[kelli]

thank you sm lol! saved me on a quiz !

[sarahthompson]

You’re good how can u teach me more than anyone else can ?

[kamsterrook]

How do I get the discriminant with the equation: 10x^2-x+4=0? I don't just want the answer because i wanna know how to properly do this but I keep getting a weird answer.
