Question

(alpha^2+beta^2)/alpha^2*beta^2

Answer 1

hey here is your answer
=======================

$= \frac{ { \alpha }^{2} + { \beta }^{2} }{ { \alpha }^{2} { \beta }^{2} } \\ = \frac{( \alpha + \beta)^{2} - 2 \alpha \beta }{ { \alpha \beta }^{2} }$
=======================
hope it may helpful to you

Answer 2

(alpha^2+beta^2+2alpha*beta-2alpha*beta)/alpha*alpha*beta*beta
=(alpha^2+beta^2+2alpha*beta-2alpha*beta)/alpha*beta*alpha*beta

(alpha+beta)^2-alpha*beta/alpha*beta*alpha*beta
