Polynomials

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication.

GCF stands for Greatest Common Factor, which is the largest polynomial that divides each term of a polynomial without leaving a remainder.

To find the GCF, factor out the common term from each part of the polynomial. The GCF is 4x.

To add polynomials, combine like terms by adding their coefficients while keeping the variable parts the same.

The sum is 5x^2 + 2x - 2.

Simplifying a polynomial means to combine like terms and reduce the expression to its simplest form.

Like terms are terms that have the same variable raised to the same power, allowing their coefficients to be combined.

The degree of a polynomial is the highest power of the variable in the expression.

The area can be found by evaluating the polynomial expression that represents the area, often involving factoring or simplifying.

The area is represented by the polynomial 2x^2 - 9x - 18 square inches.
