Answer 3

help! @ganeshie8

Answer 4

Just earlier you uhh

Answer 5

got what's called the "discriminant"
\[\Large b^2 - 4ac\]

In the quadratic formula, this expression would be inside a square root sign

Answer 6

yes and

Answer 7

So... this is really what gives the quadratic expression its "flavour" if you will.

When something is inside a square root sign, there's a case when it simply will not exist (in reals)

What sort of numbers DON'T have square roots?

Answer 8

recall that "real numbers" are precicely the numbers whose square is nonnegative

Answer 9

I'm just not as gifted with words as you guys are haha @ganeshie8

Answer 10

i have never heard \(b^2-4ac\) called the "radicand" before
on planet earth we usually say "discriminant" although i guess it really is a "radicand" since it sits inside a square root sign

Answer 11

pretty convinced the question makes no sense standalone, it refers to the quadratic formula

Answer 12

Nice handwriting ganeshie :/
How on earth did you do that with the draw tool?

Also, equal to zero, fahd? 0 is nonnegative and does have a real square root ^^

Answer 13

Correct!
terence there is some extension that allows adding pictures, colors etc to draw tool.. let me pull it up

Answer 14

ok thank you

Answer 15

@Nnesha knows about drawing extensions better than me

Answer 16

thnks @Nnesha

Answer 17

i have added that not working

Answer 18

oh that sort of extension haha

Answer 19

BTW, I know OS is rather slow (sorry guys, just calling it what it is) but it is especially slow on that "new" Microsoft browser, Edge

Is that to be expected?

Answer 20

I am on Edge too because upgrading to 10 changed my default browser... it sucks
need to switch to chrome...

Answer 21

Btw those extensions are chrome specific, but javascript doesn't bother about browser.. so you don't really need to download chrome just for those extensions..

Answer 22

Well, I guess I'll get them when I need them :D
