8-1 Add/subtract Polynomials Polynomial – a monomial or sum of monomials. Binomial – the sum of 2 monomials. Trinomial – the sum of 3 monomials. Degree of a monomial – the sum of the degree of any term in a polynomial. Degree of a polynomial – the greatest degree of any term in a polynomial. Standard form of a polynomial – the terms are ordered from greatest to least degree. Leading coefficient – the coefficient of the first term. 8-3 Multiplying Polynomials FOIL method – a method used to multiply binomials. Quadratic expression – an expression in which one variable has a degree of 2. ax2 + bx + c 8-5 Using the Distributive Property Factoring – to express a polynomial as a product of monomials and polynomials. Factoring by grouping – using the distributive property to factor. Zero product property – if the product of 2 factors is 0, at least one factor has to be 0. 8-6 Solving x2 +bc + c = 0 Quadratic equation – the equation ax2 + bx + c = 0, where a≠0. 8-7 Solving ax2 + bx + c = 0 Prime polynomial – a polynomial that cannot be written as a product of 2 polynomials with integral coefficients. 8-8 Difference of Squares Difference of two squares – 2 perfect squares separated by a subtraction sign. 8-9 Perfect Squares Perfect square trinomial – a trinomial that is the square of a binomial.
