Find the roots of a quadratic using the quadratic formula

👉 Learn how to solve quadratic equations using the quadratic formula. A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a quadratic equation.

The quadratic formula is given by x = (-b +/- sqrt(b^2 - 4ac)) / 2a, 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. Thus, to solve a quadratic equation using the quadratic formula, first identify the 'a', 'b' and the 'c' of the quadratic equation and plug them into the quadratic formula and evaluate accordingly.

I wished my math teacher was this helpful

[onehappyboi]

Man just explained a month worth of information in 4 minutes and made it work

[archu]

who else wants him as their math teacher!!!

Well, thanks for this. All this time, I thought I already "mastered" Quadratic Formula. I know how to take roots, but I didn't know you can leave a real number but not a perfect square with a radical in it. On the past days of learning whole set of Completing the Squares, there, yeah no way of getting simplified answer when there's still real but not perfect square number. All this time, I've been removing radical sign after solving b^2 - 4ac wether it's perfect square or not because it will define the nature of roots according to our system, so at this point, I thought it will be 5±61/2 (66/2 and 56/2).

I saw many videos in YouTube about how to find roots of a quadratic equations but nobody explained clearly but you helped me soo much to understand this type problems thank you so much for that sir

[babasahebgite]

Sir I am Indian but I understand it properly and easily, nice teaching

[xcl]

I understand more if i watch this than my teacher

[sudharajput]

His vocabulary is basic and understandable for every student, awesome teacher ❤

[antisocialdude]

thank you so much sir, lmao i was failing math btw

[mujtabahaider]

You are better than my teacher who has a teaching experience of more than 15 years

[iz]

Quarantine check need this kind of teacher

[rahulsai]

Thanku u so much sir for explaining me in very detail so that i can do problems easily sir move on like this so u may get more Subscribers like!!

ALL THE VERY BEST SIR MOVE ON LIKE THIS 👍👌👌😄😄😊😊😊😊

[llylylyzzz]

Thank you very much! I idmire u since the beginning of my highschool, you're my second best teacher.

[thwassashoota]

This actually helped a lot thanks a lot

[AanandilalKathpitiya]

I love my world. But when I encountered with Mathematics, Physics and Chemistry I thought stone age was the best phase of mankind!

[teslaaronyt]

0:00-0:41 My brain understands it
0:42-0:45 I figured it out in almost an hours im so dumb

[RonnievoiPerez-bqjw]

Thank you so much this helps me to catch of to my lessons

[mythic_renzo]

this guy knows how to explain this math problem very well and very easy

[Miracleedwin]

Hmmm, I think one of the ways to find a quadratic roots is the use of product sum and factors
