# Rearranging formula? Question? watch

1. ..
2. Hi

Can you give an example of a question you're stuck on?

(Original post by iamspiderman)

M^2= 2k - k^2 / 2y+ 1
This is ambiguous and isn't solvable.
3. Making p the subject is solving it because you're finding the value of it in terms of y (or the value of y in terrms of k and m in the second example), you could then find the value for y if you had k (or another equation for it / multiple equations)

Hi
I uploaded an image of the question.
It has the square root , I just got rid of it because I didn't know how to square root on this.
Ah ok great, thanks.

So squaring is a good start. The easiest way is probably to start by rearranging so that you only have the fraction with the y on one side. Can you see what you could do next?
