Question

if x/ y = a+ b / a - b show that x²+ xy/ xy- y² = a²+ ab / ab - b²​

Answer 1

Answer:

Answer:Ab(x² + y²) - xy(a² + b²) ... Prove that (ab +xy)(ax+by)>4abxy(a. play ... If A and B are symmetric matrices of the same order and X=AB+. play ... icon. (a+b)x+(a-b)y=2ab and (a+b) x-(a+ b)y =ab.
