124

Explanation:

The discriminant is equal to b^2-4ac. We just need to find our values for a, b and c and plug them into our expression for the discriminant.

This quadratic is in standard form, ax^2+bx+c. We know the following:

a=6
b=10
c=-1

Now we can plug the values in:

10^2-4(6)(-1)= 100-24(-1)= 100+24=124

The discriminant is 124
