Polynomial Types and Basic Operations
Polynomials come in different forms depending on how many terms they have. A monomial has just one term like -20 or 3xyz. A binomial contains two terms such as 10x - 8. A trinomial has three terms like x² + 3x - 3.
When writing polynomials, remember that terms are connected by addition (+) or subtraction (-) signs. Proper monomials must have whole number exponents, no variables in the denominator, and no variable exponents.
Let's practice with perimeter and area calculations! For a rectangle with length 4x+3 and width 3x+1, we can find the perimeter using P = 2(length) + 2(width). This gives us P = 2 + 2 = 8x + 6 + 6x + 2 = 14x + 8.
Try This! Find the area of the same rectangle by multiplying length × width. The formula is A = . Can you expand this expression?

Standard Form and Degrees
Polynomials should be written in standard form - arranging terms with the highest exponent first, then decreasing from left to right. For multiple variables, list them in alphabetical order (like x before y).
The degree of a monomial is found by adding up all the exponents of variables in that term. For example, 2x²y² has a degree of 4 (2+2), while 3xy has a degree of 2 (1+1). A constant number like 3 has a degree of 0.
For entire polynomials, the degree is simply the highest degree found among all its terms. For instance, 10x² - 4x + y⁵ has a degree of 5 because y⁵ has the highest exponent sum.
Remember: When a variable has no written exponent (like x), its exponent is understood to be 1.
