You can put this solution on YOUR website! 10zē+3z-3=0 I need to know what is the discriminant?
-----
Disc = b^2 - 4ac
a = 10
b = 3
c = -3
-----
Disc = 10^2 - 4*10*-3
= 100 + 120
= 220
There's no mystery about it.
You can put this solution on YOUR website! When the equation has the form , then the roots are found
using the quadratic formula:
The discriminant is:
If the discriminant is positive, both roots are real
If the discriminant is negative, both roots are imaginary
If the discriminant is zero, there is 1 real root
------------------
Your equation is:
and the discriminant is:
This result is positive, so there are 2 real roots
Here is the plot:
