Question

What is the discriminant of the equation?
3x^2 + 10x + 4 = 0
Question options:

19

52

148

-41

Answer 1

The discriminant is the term under the radical sign in the quadratic formula.

x=(-b+-(b^2-4ac)^(1/2))/(2a)

It is the b^2-4ac part.  (a,b,c from the standard quadratic of form ax^2+bx+c)

In this case:

10^2-4*3*4

100-48

52
