If p , q, n , l > 0 and the ratio of the roots of equation : lX^2 + nx + n = 0 be p:q then proove that p/q^1/2 + q /p^1/2 – n/l^1/2 = 0
Hello student, the ratio is p : q so let roots bept and qt. so pt + qt = - n/l => p + q = - n/(lt) and pqt^2 = n/l => pq = n/(lt^2) now (p/q)^1/2 + (q/p)1/^2 = (p + q)/(pq)^(1/2) =...
