Answer
Discriminant: $0$;
Roots/solutions: Discriminant is zero which means that the quadratic equation will have one real solution.
Work Step by Step
Let us determine the discriminant of the quadratic equation $9x^2-12x+4=0$
which can be calculated as: $D=b^2-4ac=(-12)^2-(4)(9)(4)=0$
This implies that $D$ represents a zero value.
Hence, our answer is:
Discriminant: $0$;
Roots/solutions: Discriminant is zero which means that the quadratic equation will have one real solution.
