If a 2 +2bx+c=0 is negative then value of det a b ax+b b c bx+c = 0 ax+b bx+c 0 Prove this plz........
Dear Sohini, This is a very simple problem. It is given that a < 0 and 4b - 4ac > 0 0r a < 0 and b2 - ac > 0 Now, what you simply have to do is solve the given determinant using the properties which you have learnt and when you expand the equation you have to use a < 0 and b2 - ac > 0, use it and you will get the value of the determinant as 0.
