Find the value of the discriminant. then describe the number and type of roots for the equation.
–3x2 – 18x + 5 = 0
the discriminant is 324. because the discriminant is greater than 0 and is a perfect square, the two roots are real and rational.
the discriminant is –384. because the discriminant is less than 0, the two roots are complex.
the discriminant is 384. because the discriminant is greater than 0 and is not a perfect square, the two roots are real and irrational.
the discriminant is –264. because the discriminant is less than 0, the two roots are complex.
