Let $$a,b$$ and $$c$$ be nonzero real numbers such that $$\frac{1}{a} + \frac{1}{b} + \frac{1}{c} = 0.$$ Compute $$\frac{bc}{a^2} + \frac{ac}{b^2} + \frac{ab}{c^2}.$$

To be honest, I would just plug in values.

Let a = 2, b = 2, and c = -1.

Then simply solve.

(However, CoolStuffYT's way works as well!)

Thanks Alan,

I was wondering how to do that one formally.

Thanks Coolstuff too :)
