Given that alpha and beta are the roots of the equations x ^ 2 - (1 + n ^ 2) * x + 1/2 * (1 + n ^ 2 + n ^ 4) 0 و (alpha + beta) = 1 + n ^ 2 ;( alpha beta)= (1 + n ^ 2 + n ^ 4)/2 Now, (alpha ^ 2 + beta ^ 2) =(1+n^ 2 )^ 2 -2* 1 2 (1 + n ^ 2 + n ^ 4 ) ( alpha^ 2 + beta^ 2 )= 1 + n ^ 4 + 2n ^ 2 - 1 - n ^ 2 - n ^ 4 (alpha ^ 2 + beta ^ 2) = n ^ 2 (alpha ^ 2 + beta ^ 2) = (alpha + beta) ^ 2 - 2alpha*beta
