To use the quadratic formula to solve the equation \( 10x^2 - 4x + 1 = 6x^2 \), we first need to rearrange the equation into standard form \( ax^2 + bx + c = 0 \).

  1. Rearranging the equation:

    \( 10x^2 - 4x + 1 - 6x^2 = 0 \)

    Combine like terms:

    \( (10x^2 - 6x^2) - 4x + 1 = 0 \)

    This simplifies to:

    \( 4x^2 - 4x + 1 = 0 \)

  2. Identifying coefficients:

    Here, we have:

    • \( a = 4 \)
    • \( b = -4 \)
    • \( c = 1 \)
  3. Using the quadratic formula:

    The quadratic formula is given by:

    \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

    Now, substitute the values of \( a \), \( b \), and \( c \):

    \[ x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4 \cdot 4 \cdot 1}}{2 \cdot 4} \]

    Simplifying this gives:

    \[ x = \frac{4 \pm \sqrt{16 - 16}}{8} \]

    \[ x = \frac{4 \pm \sqrt{0}}{8} \]

  4. Simplifying further:

    Since \( \sqrt{0} = 0 \), we have:

    \[ x = \frac{4 \pm 0}{8} \]

    Thus:

    \[ x = \frac{4}{8} = \frac{1}{2} \]

  5. Conclusion:

    The solution to the equation \( 10x^2 - 4x + 1 = 6x^2 \) is

    \[ x = \frac{1}{2} \]

This is the simplest form of the solution.
