#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#
