AMEN.. Discriminant, Delta help i am suffering... (3 Viewers)

[HeroicPandas]

D implies D = 0 OR D > 0

For D=0, same root
D>0, different root

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
D >= implies D = 0 OR D > 0

Thank you guys so much deswa1 and asianese, THANKS SO MUCH!

 

[asianese]

is that a bad AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHH or a good AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHH

 

[asianese]

oh its a good one

 

[HeroicPandas]

I still have one annoying issue, when do i use DELTA greater or equal to zero

 

[asianese]

'FOR REAL ROOTS, DELTA 0'

 

[HeroicPandas]

'FOR REAL ROOTS, DELTA 0'

So if i see IF THIS QUADRATIC HAS REAL ROOTS i think of D>=0

D>0 when distinct pops up?

 

[asianese]

Yessssssssssssssssssssssssssssssssssssss! Yayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy!

 

[barbernator]

bad troll is bad.

Ok- A quadratic either has TWO real roots or NO real roots- it can't have just one. If the discriminant (D) is GREATER THAN OR EQUAL TO zero, then it will have two real roots. If it is less than zero, it will have no real roots. If and only if the discriminant is equal to 0, the two roots will be the same.

So:

D>=0 -> two real roots
D>0 -> two real roots that ARE NOT the same
D=0 -> two real roots that ARE the same
D<0 -> no real roots

Make sense?

Just curious, HeroicPandas were you the one that made the thread a while back saying ext 1 was too easy ?
