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

Best ResponseYou've already chosen the best response.11) R1+R3 2) R1R2 3) take 2 as a common factor from R1 4) R3R1 5)R2R3 "you will find 3 Zero's in the determinant" 6) find the value of the final determinant and you'll get the answer
