Roots of a Quadratic Equation

Consider the quadratic equation given by:

$$x^2 - 4x + 3 = 0$$

To determine the roots of this equation, apply the quadratic formula:

$$x = \f\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

where $$a$$, $$b$$, and $$c$$ are the coefficients of the equation $$ax^2 + bx + c = 0$$. Here, identify the values of $$a$$, $$b$$, and $$c$$ from the given equation and calculate the roots. Provide your answer as a decimal in the grid below.
