Step-by-step explanation:

alpha + beta = - ( coefficient of x) / coefficient of x2)

alpha * beta = constant / coefficient of x2

alpha + beta = - ( -7) / 2 = 7/2

alpha. beta = 5/2

alpha / beta + beta / alpha

= ( alpha(sqr)+ beta (sqr)/ alpha. beta

= (( alpha + beta) sqr - 2*alpha. beta )/alpha*beta

= ( 49/4 - 5 )/ (5/2)

= (29/5) * ( 2/5)

= 58/25
