Firstly, you should recognize the relevant numbers which are 23 and 29. Now let us work out. Every even number is divisible by two, hence not prime. So we can exclude 22, 24, 26 and 28. Meanwhile 21, (24) and 27 are divisible by three. 25 is divisible by 5. The remaining numbers 23 and 29 have no divisors other than 1 and the number itself, hence they are the prime numbers.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
