Polynomials are algebraic expressions with variables and coefficients. This overview covers evaluating polynomials, performing operations like addition and subtraction, and techniques for factoring. It also explains simplifying polynomial fractions and using long division for division. The Factor Theorem, a tool for identifying polynomial factors, is highlighted as a key concept for algebraic mastery.

Polynomials are algebraic expressions consisting of variables and coefficients linked by addition, subtraction, and multiplication
Each term of a polynomial is the product of a coefficient and a variable raised to a non-negative integer exponent
Polynomials are typically presented in standard form with terms ordered from highest to lowest exponent, and the degree is the highest exponent of the variable
Evaluating a polynomial involves substituting a specific value for the variable and performing arithmetic to find the result
Polynomial addition and subtraction are carried out by combining like terms using the distributive property and carefully managing the signs of each term
Factoring polynomials is the process of decomposing them into products of simpler polynomials
Simplifying polynomial fractions involves factoring the numerator and denominator and reducing common factors to their lowest terms
Examples of simplifying polynomial fractions include canceling common factors and factoring the numerator and denominator
Polynomial division is analogous to long division with numbers, involving dividing the leading term of the dividend by the leading term of the divisor and repeating until the remainder's degree is less than the divisor's degree
The Factor Theorem states that if a polynomial has a value of zero for a specific value of x, then x - p is a factor of the polynomial
The Factor Theorem can be applied by testing potential values of x until the polynomial equals zero, then dividing the polynomial by x - p and factoring the resulting quotient further if possible
