A polynomial is a mathematical expression consisting of variables (often represented by letters like x or y or a or e or s), coefficients (numbers multiplying these variables), and exponents (which are non-negative integers). In simpler terms, it’s an expression of terms involving adding, subtracting, and multiplying variables raised to whole number powers.

Explanation: The image shows a breakdown of a polynomial equation, where variables are multiplied by numbers (coefficients) and combined with a constant value.

Adding and subtracting polynomials involves combining or separating terms with similar variables and their corresponding coefficients. To add or subtract polynomials, align like terms (those with the same variable and exponent) and perform the arithmetic operations (addition or subtraction) on their coefficients.
