Solving using the quadratic formula

[@JvLRIII]

Wow! Thanks a lot

[@brianmclogan]

Happy to help

[@latrinahardee2257]

How would I express this in interval notation?

[@heidyortega8164]

Gracias me ayudó!

[@dexterjamero1996]

so is this how you find b in order to solve using the quadratic formula?

[@brianmclogan]

in this example b is 0

@@brianmclogan ok thank you

[@brianmclogan]

cheers! 👍

[@TaitHarvey]

what if b was 1 what would you do then? I have a problem where I have ended up with 1+ or - 12 times the square root of 3@@brianmclogan

[@jeovany1945]

did you get 2 radical 6 from 4.6, also why 4.6 and not another paired factor?

[@mjnikohwebb5736]

Thanks! This solved my homework😂

[@brianmclogan]

awesome!

So if I have x^2+6=0 , is it the same process??

[@Souren17]

The answers would be imaginary numbers, so with the formula you would get + or - √-6 which you can write as + or - i√ 6

[@nehasaklani4211]

x^2-8=0 solve this

[@brianmclogan]

say process as the video, just simplify the radical, try mathway
