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,

  • a = 9
  • b = -12
  • c = 4

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.

Answer:

0

Step-by-step explanation:

The general equation is ax^2 + bx + c = 0

and the discriminant is b^2 - 4ac.

For 9x^2 - 12x + 4 = 0, the discriminant is (-12)^2 - 4*9*4

= 144 - 144

= 0

A discriminant of 0 means there is one zero. More accurately since a quadratic equation has to have 2 zeroes the answer is  '1  zero Multiplicity 2.'
