Answer:
Discriminant: 0; 1 real solution
Step-by-step explanation:
To find the discriminant use the formula: b^2 - 4ac.
In this quadratic equation, 9x^2 - 12x + 4 = 0,
Substitute these values into the discriminant equation.
(-12)^2 - 4(9)(4)
Evaluate the exponent and multiply 4 * 9 * 4.
144 - 144
Subtracting these two numbers together gives you 0; the discriminant is 0.
Based on this discriminant you know that there is only 1 real solution to the quadratic equation.
