To subtract polynomials, you should first recognize that polynomials are algebraic expressions consisting of variables raised to non-negative integer powers, and coefficients. Subtracting one polynomial from another essentially involves dealing with each like term individually. The process is to align corresponding terms, change the signs of the terms of the polynomial being subtracted, and then […]

To classify the polynomial equations, I always start by observing the terms. A term consists of a coefficient and a variable raised to a power, which is referred to as its degree. A polynomial might have one or multiple terms, each made distinct by their coefficients or exponents. For instance, in the polynomial $7x^2 + […]
The sum of polynomial functions is the result of adding two or more polynomial expressions, which are algebraic expressions that include variables and coefficients.

A discrete function is a type of function in which the domain is a set of individual points, typically integers or certain rational numbers. This distinct nature means the function does not have values between these points, separating it from its counterpart, the continuous function, which has a value defined over an entire interval. For […]
