Consider the non-linear expression given by:
$$y = x^2 - 4x + 3$$
To find the x-intercepts of this equation, we need to determine the values of x for which $$y = 0$$. To do this, set the equation equal to zero and solve for x:
$$0 = x^2 - 4x + 3$$
Once you find the x-intercepts, report your answer in the grid-in format as both decimal and fraction representations.
