If roots of the

Answer»

`2b^(-1)= a^(-1) + c^(-1)`
`2C^(-1)= a^(-1) + B^(-1)`
`2A^(-1)= b^(-1) + c^(-1)`
None of these

Solution :(i) If sum of all coefficientis zero, then 1 `c/a` are the root of ` ax^(2) + bx + c = 0`.
(ii) If the sum of coefficient is 0, then 1 and `c/a` are the ROOTS of the equation.
(III) Use productof the roots concept.
