Assertion (A): The polynomial p(y)=y^2+4 y+3 has two zeroes. Reason (R): A quadratic polynomial can have at most two zeroes.
Assertion (A) : The polynomial $\displaystyle p(y)=y^{2}+4 y+3$ has two zeroes.
Reason (R) : A quadratic polynomial can have at most two zeroes.
Official answer
(B)
Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
