HELP!!! A LOT OF POINTS!!!
Tpy6a [65]

Answer: Last option.

Step-by-step explanation:

For this exercise you need to find the Discriminant.

The formula used to find the Discriminant, is the following:

D=b^2-4ac

In this case, given the Quadratic equation:

6x^2-2x+7=0

You can identify that:

a=6\\b=-2\\c=7

Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.

You get that this is:

D=(-2)^2-4(6)(7)\\\\D=-164

By definition, if:

 D

Then the Quadraitc equation has 2 nonreal solutions.
