0
1
2

last option

Step-by-step explanation:

The formula to find the Discriminant is:

Given the quadratic equation , you can identify that:

Now, you can substitute values into the formula  , then:

As the Discriminant is greater than 0 (), then the quadratic equation   has two distinct real solutions.

ANSWER

2

EXPLANATION

The given quadratic equation is

Comparing to

We have a=1, b=-1 and c=-6

The discriminant is given by the formula,

Plug in the values to get,

Since the discriminant is positive, the equation has two real roots.
