The cube has 8 vertices.

The number of ways to construct a triangle is (8 x 7 x 6) = 336 .

But there are 6 ways to wind up with the same triangle.

So the number of distinct ones is ( 8! )/( 5! x 3! ) = 56 .

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
