Hi guys,

Can anybody point me in the right direction to solve this equation? I’m trying to develop my math skills in preparation for an OU degree this Autumn. But my mind has just gone blank and can’t understand how to solve it

The question:

Rearrange the following expression to make R the subject, where R > 0

h = R^2 / L + L

I have lots more of these practise questions to get through, so this is just to help me figure out how to solve it correctly

also, I should mention that I have another question which I’ve made a separate post about as it’s not directly related to the problem in this thread (hence 1 of 2 in title)

Thanks guys!
