for the following equation state the value of the discriminant and then describe the nature of the solution 11x^2+9x+11=0

What is the value of the discriminant?
Which one of the statements below is correct?

A. The equation has two imaginary solutions.
B. The equation has two real solutions.
C. The equation has one real solution.

  • College Algebra 2 - ,

    The discriminant for the equation
    Ax+By+C=0
    is sqrt(B²-4AC)

    If the quantity under the square-root sign is >0, there are two real roots. If it is zero, there is one real root, in fact, two coincident real roots. If it is negative, the equation has two imaginary roots.

    Post you answer if you need a check.
