Question

If one zero of the polynomials (ax² + bx + c) is the reciprocal of the other, and (a ≠ 0), then which of the following must be true?

Assertion(A): Both zeroes of the quadratic polynomial x² – 2kx + 2 are equal in magnitude but opposite in sign then value of k is ½. Reason(R): Sum of zeroes of a quadratic polynomial ax² + bx + c is −b/a

Assertion(A): If the sum of the zeroes of the quadratic polynomial x² –2kx+8 is 2 then value of k is 1. Reason(R): Sum of zeroes of a quadratic polynomial ax²+bx+c is −b/a

Assertion(A): If the product of the zeroes of polynomial x² +3x +k is -10, the value of k is -2 Reason(R): Sum of the zeroes of quadratic polynomial ax²+bx+c is −b/a
