Hi I want to break out L from this equation and I have some problems in doing so

M = -p*l - (q*l^2)/2

I get

L = (M + p) *2 / -q

Is that correct? if not could someone correct me and help me write it properly

Thank you

First multiply throughout by 2, we get

2M = -2pl -ql^2

That is

ql^2 + 2pl + 2M = 0, it is a quadratic now you can proceed to solve it for l - Jan 9th 2014, 06:28 PMJeanGunterRe: How can i solve L for this equation algebraically
Thanks for this answer, actually we have same problem even though this post last April now I need it. :)
