So the slope of my secant line has simplified to 6 times my change in x plus my change in x squared, all of that over my change in x. Now we can simplify this even more. Let's divide the numerator and the denominator by our change in x. And I will switch colors just to ease the monotony. So my slope of my tangent of my secant line, the one that goes through both of these, is going to be equal if you divide the numerator and denominator. This becomes 6. I'm just dividing numerator and denominator by delta x.
