Use the discriminant to determine the number of real solutions to the quadratic equation. n^2 − n − 6 = 0 what is the number of real solutions? select the correct answer below:

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.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

c
