2x^2 -3x-5=0 what is the discriminant?
----
a = 2
b = -3
c = -5
---
Discriminant: b^2-4ac
---------
b^2-4ac = (-3)^2-4*2*-5 = 9+40 = 49
------
Since the discriminant is positive the quadratic
has 2 unequal Real solutions.

2x^2 -3x-5=0 what is the discriminant?

The discriminant is b^2 - 4ac

2x^2 - 3x - 5 = 0
a = 2, b = -3, c = -5

b^2 - 4ac
= (-3)^2 - 4(2)(-5) {substituted into the discriminant}
= 9 + 40 {evaluated exponent and multiplied left to right}
= 49 {added 9 and 40}

Also, this means there would be 2 real number solutions to the equation
