If the equations `x^(2) -px +q=0` and `x^(2)+qx-p=0` have a common root, then which one of the following is correct?

A

`(b_1^2+b_2^2+b_3^3)=2(b_1.b_2.b_3+b_3.b_1)-4(c_1+c_2+c_3)`

B

`(b_1^2+b_2^2+b_3^3)=2(b_1.b_2+b_2.b_3+b_3.b_1)+4(c_1+c_2+c_3)`

C

`(b_1^2+b_2^2+b_3^3)=2(c_1.c_2+c_2.c_3+c_3.c_1)-4(b_1+b_2+b_3)`

D

`(b_1^2+b_2^2+b_3^3)=4(b_1.b_2+b_2.b_3+b_3.b_1)-4(c_1+c_2+c_3)`
