Finding Zeros of Quadratic Functions by Graphing & Factoring

[@dalekmasterblaster585]

Posted 5 years ago and still super helpful. Nice!

[@skater10153]

I got finals tomorrow and thanks to you, i know im gonna get an A! You're a Saint my friend!

[@MartyBrandl]

I'm glad it was helpful! Just south of Canada in Minnesota, USA. :-)

[@kuya_akie]

Oops, you goofed up. I understood the video though, very clear and detailed. Thanks!

[@LOLaquillis]

hello im from the philippines and your video presentation helps me to solve my problem in our lesson so thanks. :D

[@FKLQ99]

I love your voice and the way you express. It makes the idea very understandable. Thank you :)

[@MartyBrandl]

@bmx4life519 :-) You can always fast-forward if you need to! Then it's there for those that might need it. Thanks for the feedback!

[@derrickt.1487]

confused me just a little when u made the mistake and had to back track, but im glad u did go back on straighten it out! overall a good video to help me understand this a little better

[@andrewpop5256]

What if you only have 2 terms? How will you find the zeros. EX: -X squared + 2X

[@slimjim681]

would the purple one have a multiplicity of 2

[@BeautifulRose16]

With my exam in 2weeks, i've been really struggling. This really helped! Thanks a ton. Love your accent! Are you Canadian?

[@AffinityKi]

You're help is just as great as khan's !

[@tomashaase628]

how do u do it when cant factor????

[@MartyBrandl]

Then we can use another method of solving, such as completing the square or the quadratic formula. You search for channel for videos about both! I hope that helps! :-)

[@vimboy10]

Thanks for the tutorial dude! :) This thing would really help me in my exam tomorrañow

[@jordanromero8843]

How did you do on your exam

[@Mcdonalds_Neuviotter]

is g(x) and h(x) the same as f(x)?

[@MartyBrandl]

It stands for the same thing. Correct! :-)

[@Mcdonalds_Neuviotter]

Marty Brandl thanks!

[@mcdiamonds8004]

How do u do it with fraction :/

[@MartyBrandl]

Graphing by hand and factoring wouldn't be the best options with fractions. I would suggest using the quadratic formula or a graphing calculator. I hope that helps! :-)

[@justinyi5341]

Also you said the -1 point is when x = 0, but it is supposed to be when y = 0.

[@lawrenceadhinatha6480]

Thanks man. This really helped!

[@MartyBrandl]

That is correct!

[@justinyi5341]

You have a mistake in the first problem at 3:03. It was supposed to be -1(x-5)(x+1).

[@justinyi5341]

+Justin Yi Never mind

[@damienstein5504]

makes no sense....where did the neg 1 go

[@vbllphain]

Thank you!!! Helped a lotttt:)

[@maui044]

SURE DOES!

[@justanassassin]

I think there's an error

[@MartyBrandl]

Let me know where and I'll double-check! :-)

[@AffinityKi]

*your. ^can't believe I did that

[@vimboy10]

Tomorrow I mean.. :)

[@MrMarkapple143]

Equaaaaaaaaaations XD
