what is the discriminant for
$9x^2 - 6x + 1 = 0$ ?
enter only the numerical answer.

Explanation:

Step1: Recall discriminant formula

For a quadratic equation \(ax^2 + bx + c = 0\), the discriminant \(D\) is given by \(D = b^2 - 4ac\).

Step2: Identify coefficients

In the equation \(9x^2 - 6x + 1 = 0\), we have \(a = 9\), \(b = -6\), and \(c = 1\).

Step3: Calculate discriminant

Substitute the values of \(a\), \(b\), and \(c\) into the discriminant formula:
\[

$$\begin{align*} D&=(-6)^2 - 4\times9\times1\\ &= 36 - 36\\ &= 0 \end{align*}$$

\]
