If alpha, beta be the roots x^(2)-px+q=0...

If `alpha, beta` be the roots `x^(2)-px+q=0 and alpha', beta'` be those of `x^(2)-p'x+q'=0`, then the value of
`(alpha-alpha')^(2) +(beta-alpha')^(2) +(alpha-beta')^(2)+(beta-beta')^(2)=`…..

A

`2 { p^2 -2q +p^(')^2 - 2q-pp'}`

B

`2 {p^2 - 2q+p^(')^2 -2q^(')-qq}`

C

`2{p^2-2q-p^(')^2-2q'-pp}`

D

`2{p^2-2q-p'^2 - 2q' -qq}`
