Urgent Help - OCR C3

All fine so far (although hard to read because your picture is sideways).

You are trying to show that there are exactly two stationary points. So you need the quadratic you have obtained to have certain properties. How can you check that it has the properties you want? If you have a go at this, you'll find that they've set the question up so that it is easy to do it.

So should I solve the quadratic that I have obtained to determine the coordinates of the stationary points. But how will that work because when I solve for x, I will give me values of x in terms of m, right?

You don't need to show it. You simply need to show that for all $m\in \mathbb{R}$ the discriminant of the quadratic is greater than 0 as then there are 2 distinct solutions hence 2 stationary points.

I find that hard to understand. I thought the discriminant if greater than will determine if the quadratic has two real roots on the x-axis (2 distinct roots). But how does that mean 2 stationary points?
