Quadratic Solutions Discriminant

How many solutions are there?

• 0

• 1

• 2

• Cannot be determined

The discriminant is

• aX²  + bX  +  c

• b - 4ac

• b² - 4ac

• b² + 4ac

For the function below, is the discriminant positive, negative, or zero?___________y = x² + 4x + 4

• Positive

• Negative

• Zero

• Not Sure

How many solutions?

• 1 Solution

• 2 Solutions

• No Solution

• Empty set. Does not equal to zero.

The ____________ is used to determine the number of solutions to a quadratic equation.

If the discriminant is negative, then the quadratic has:

• 1 Rational Solution

• 2 Rational Solutions

• 2 Irrational Solutions

• 2 Complex Solutions

If the discriminant is negative, you will have....

• two real solutions

• two irrational solutions

• two imaginary solutions

• one solution

When the discriminant is (a)   there will be two imaginary roots.

• Negative

• Zero

• Positive

If the discriminant is positive but NOT a perfect square, then the quadratic has:

• 1 Rational Solution

• 2 Irrational Solutions

• 2 Rational Solutions

• 2 Complex Solutions

Find the value of the discriminant. (Type # only.)
