The sign of the product of four integers depends on the signs of the individual integers. There are 4 cases:

1) When all 4 integers share the same sign and all are non-zero (either all are positive or all are negative), the product is positive.

2) When 3 of the 4 integers share the same sign and all are non-zero (3 are positive and 1 is negative; or 3 are negative and 1 is positive), the product is negative.

3) When 2 of the integers are positive non-zero and the other 2 of the integers are negative non-zero, the product is positive.

4) If even one of the integers is zero, the product is zero (no sign - it is neither positive nor negative).

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
