1. The total number of factors of a prime number is

The HCF and LCM of 12, 21, 15 respectively are

The prime factorization of 3825 is:

The zeroes of the polynomial x² ─ 3x ─m(m+3) are

If one of the zeroes of the quadratic polynomial x² + 3x + k is 2, then the value of k is:

The quadratic polynomial, the sum whose zeroes is ─ 5 and their product is 6, is

The zeroes of the quadratic polynomial x² + kx + k, where

k ≠ 0,

Assertion(A): 2 x² + 14x + 20 have two zeroes.

Reason(R): A quadratic polynomial can have at most two zeroes.

The value of k for which the system of equations x + y _ 4 = 0 and 2x + ky = 3, has no solution, is:

The pair of equations x = 0 and x = ─ 4 has
