Just earlier you uhh
got what's called the "discriminant" \[\Large b^2 - 4ac\] In the quadratic formula, this expression would be inside a square root sign
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?
recall that "real numbers" are precicely the numbers whose square is nonnegative
I'm just not as gifted with words as you guys are haha @ganeshie8
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
pretty convinced the question makes no sense standalone, it refers to the quadratic formula |dw:1439052445971:dw|
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 ^^
Correct! terence there is some extension that allows adding pictures, colors etc to draw tool.. let me pull it up
ok thank you
@Nnesha knows about drawing extensions better than me
i have added that not working
oh that sort of extension haha
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?
I am on Edge too because upgrading to 10 changed my default browser... it sucks need to switch to chrome...
Well, I guess I'll get them when I need them :D
