Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion: P(x) = 4x^{3}x^{2}+5x^{4}+3x2 is a polynomial of degree 3.
Reason: The highest power of x in the polynomial P(x) is the degree of the polynomial.
Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : (2  √3) is one zero of the quadratic polynomial then other zero will be (2 + √3).
Reason : Irrational zeros (roots) always occurs in pairs.
Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion: If one zero of polynomial p(x) = (k^{2}+4)x^{2}+13x+4k is reciprocal of the other, then k=2.
Reason: If (xa) is a factor of p(x), then p(a) = 0 i.e., a is a zero of p(x).
