Question

Assertion(A): The roots of the quadratic equation x² + 2x + 2 = 0 are imaginary Reason(R): If discriminant D = b² – 4ac < 0 then the roots of quadratic equation ax² + bx + c = 0 are imaginary.

Assertion (A): The polynomial p(x) = x² + 4 has no real zeros. Reason (R): A quadratic polynomial ax² + bx + c has real zeros only if b² − 4ac ≥ 0.
