What is the roots/solutions of 4x²-12x+9

The given quadratic equation is:

\[
4x^2 - 12x + 9 = 0
\]

This equation can be solved by factoring or using the quadratic formula. Let's attempt factoring first.

### Factoring the quadratic expression:
The equation can be rewritten as:

\[
(2x - 3)^2 = 0
\]

To solve for \(x\), we take the square root of both sides:

\[
2x - 3 = 0
\]

Solving for \(x\):

\[
x = \frac{3}{2}
\]

### Conclusion:
The solution to the equation \(4x^2 - 12x + 9 = 0\) is:

\[
x = \frac{3}{2}
\]

It is a **repeated root** (also known as a double root), meaning the quadratic has only one unique solution.
