2X2 + 3X - 4 = 0

the discriminant is,

b2 - 4ac

32 - 4(2)(- 4)

9 + 32 = 41

41 > 1

this means there are two real roots to this equation

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
