AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHDimplies D = 0 OR D > 0
For D=0, same root
D>0, different root
D >= implies D = 0 OR D > 0
AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHDimplies D = 0 OR D > 0
For D=0, same root
D>0, different root
So if i see IF THIS QUADRATIC HAS REAL ROOTS i think of D>=0'FOR REAL ROOTS, DELTA0'
YES! ok thanks for explaining to meYessssssssssssssssssssssssssssssssssssss! Yayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy!

SAME!!!!!! I can now sleep in peace tonightBarb...I was jumping up and down and cheering, i was that happy.
+1Ok- 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?
yepJust curious, HeroicPandas were you the one that made the thread a while back saying ext 1 was too easy ?
Too much retard in that thread. Far too much.
Please do not remind me about that, I have changed nowJust curious, HeroicPandas were you the one that made the thread a while back saying ext 1 was too easy ?
