Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:
First, arrange the expression or equation in ax^2+bx+c = 0.
Add both sides by 9.
Compare the coefficients so we can substitute in the formula.
Substitute a = 1, b = 6 and c = 9 in the formula.
Since D = 0, the type of solution is one real root.
