If one of the roots of the equation ax2+bx+c=0 is reciprocal of the other, then choose the correct option.
Let’s assume one of the roots is α. If the roots are reciprocal of each other, the other root will be 1α
Observe that the product of both the roots is 1 i.e. α×1α=1 The formula for product of the roots of the quadratic equation is ca.
Hence the correct option is c = a .
