• # question_answer Assertion (A): $(2-\sqrt{3})$ is one zero of the quadratic polynomial then other zero will be $(2+\sqrt{3})$. Reason (R): Irrational zeroes (roots) always occurs in pairs. A) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). B) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A). C) Assertion (A) is true but reason (R) is false. D) Assertion (A) is false but reason (R) is true.

 [a] As irrational roots/zeroes always occurs in pairs therefore, when one zero is $(2-\sqrt{3})$then other will be$2+\sqrt{3}$. So, both assertion and reason are correct and reason explains assertion.
