    x-intercept is a point when line intersect x-axis when `y=0` so substitute y f0r 0 to find x-intercept y-intercept is a point where line cross y-axis when `x=0` so substitute x for 0 to find y-intercept

    how would you cancel out (x-3)(x+1) ?

    You could multiply the whole fraction by (x-3)(x+1), they cancel out.
