show that :I b^2+c^2 a^2 a^2 I I b^2 c^2+a^2 b^2 I I c^2 c^2 a^2+b^2 I =4a^2b^2c^2 where I ... I is a sign of determinant

    can we do something like R1-R2-R3

    i think after R1-R2-R3 we can take -2 common from R1 then R2-R1 and again R3-R1

    1) R1+R3 2) R1-R2 3) take 2 as a common factor from R1 4) R3-R1 5)R2-R3 "you will find 3 Zero's in the determinant" 6) find the value of the final determinant and you'll get the answer
