The determinant equal to
detailed solution
Correct option is D
we have,b2−ab b-c bc-acab−a2 a-b b2−abbc−ac c-a ab-a2=b(b−a) b-c c(b−a)a(b−a) a-b b(b−a)c(b−a) c-a a(b−a)=(b−a)2b b-c ca a-b bc c-a a on taking (b-a) common C1 and C3 each=(b−a)2b−c b-c ca−b a-b bc−a c-a a ∵C1→C1−C3=0since two columns C1 and C2 are identical ,so the value of determinant is zeroSimilar Questions
