To find the HCF you first have to write the numbers as their prime factors:

36 = 2x2x3x3

75 = 3x5x5

The next step is to identify any common prime factors. In this case both numbers have 3 as a prime factor. Thus the HCF is 3.

To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900

Thus the LCM of 36 and 75 is 900.

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
