If the discriminant is 0 you will have:

• no real solutions

• two real solutions

• 1 real solution

• 1 imaginary solution

Having imaginary roots mean the discriminate is

• Greater than 0

• Less than 0

• Eqaul to 0

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

• two real solutions
• two irrational solutions
• two imaginary solutions
• one solution
