If one root is square of the other root of the equation , then the relation between is
Explanation for the correct option.
Let the one root of the given equation be then the other root will be .
Now, we know that the sum of these roots will be equal to and their product will be equal to . From this we construct two equations,
Now, in equation , apply the cube on both the sides,
Apply the algebraic identity , then
Apply the value of from equation ,
Hence, the correct option is (A).
