## tmybby one year ago What is the number of real solutions? 6x^2-7x-1=0

1. mathstudent55

Are you familiar with the quadratic formula?

2. tmybby

some what

3. mathstudent55

The part inside the square root symbol is called the discriminant. It is b^2 - 4ac

4. mathstudent55

Calculate the discriminant using the a, b, and c values of your equation. Then if the discriminant is: - greater than zero, there are 2 real solutions - equal to zero, there is one real solution - less than zero, there are no real solutions.
