For the following equation, state the value of the discriminant and then describe the nature of the solutions:
18x^2+5x-9=0
1. What is the value of the discriminant?
b^2-4ac = 5^2 - 4*18*-9 > 0
=====================================
2. Are there two imaginary solutions? no
----------------------------------------
3. Are there two real solutions? yes
----------------------------------------
4. Only one real solution? no
