To solve this type of problem, you need to evaluate the discriminant, which is the expression under the square root in the quadratic formula:
b2 - 4ac
Your equation is 9x2 - 12x + 4, so a = 9, b = -12, and c = 4. Plug those values into the discriminant and compute the value:
- If the discriminant > 0, then there are two real solutions to the equation
- If the discriminant = 0, then there is one real solution to the equation
- If the discriminant < 0, then there are two complex (nonreal) solutions
That's it.
