What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents. For example, 2x^2 + 3x + 5 is a polynomial.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression. For example, in the polynomial 4x^3 + 2x^2 + 7, the degree is 3.

How do you add polynomials?

Back

To add polynomials, combine like terms. For example, (3x^2 + 2x) + (4x^2 + 5) = 7x^2 + 5.

What is the square of a binomial?

Back

The square of a binomial (a + b)^2 is equal to a^2 + 2ab + b^2. For example, (3x - 2)^2 = 9x^2 - 12x + 4.

How do you factor a polynomial?

Back

To factor a polynomial, find the greatest common factor (GCF) and use techniques like grouping or applying special formulas (e.g., difference of squares).

Front

What is a monomial?

Back

A monomial is a polynomial with only one term, such as 5x^3 or -2.

How do you divide a polynomial by a monomial?

Back

To divide a polynomial by a monomial, divide each term of the polynomial by the monomial. For example, (15x^9 - 8x^3) ÷ 3x^3 = 5x^6 - rac{8}{3}.
