I got this annoying problem I can't seem to get around, I know there's a trick somewhere in the book for this...I think there is, anyhow, I need to solve the following equation for x:
(s^2 - 2sx + x^2)(a) = (x^2)(b)
Each time I try to mess around with x and s, I'm unable to break the 2sx term and it's rly getting to me, at my last step I got to this useless mess:
(s^2 - 2sx)/(x^2) = (b/a)(x^2)
Any tips/tricks highly appreciated, spanks!
