Answer:
AH! Quadratic Equations?!?!?!??
Step-by-step explanation:
The discriminant is the this part of the quadratic formula(the one in parentheses)
[tex]x=\frac{-b+-(\sqrt{b^{2}-4ac }) }{2a}[/tex]
So let's take it out!
[tex]b^{2} -4ac[/tex]
(if you don't know what a quadratic equation is, why are you doing this to yourself?)
REMINDER: Quadratic equation: x^2+bx+c=0
So let's input the values into this and find out!
It is more likely that the last three will have a negative discriminate so:
3:
49-12
37
Nope! Positive!
4:
16+8
Nope!Positive!
5:
9-16
Found It!
Hope this helps.
FYI it's option 5
