What is a linear polynomial?

Back

A linear polynomial is a polynomial of degree 1, which has the form ax + b, where a and b are constants. For example, 2x + 3 is a linear polynomial.

FLASHCARD QUESTION

Front

What is a quadratic polynomial?

Back

A quadratic polynomial is a polynomial of degree 2, which has the form ax² + bx + c, where a, b, and c are constants. For example, x² + 2x + 1 is a quadratic polynomial.

FLASHCARD QUESTION

Front

What is a cubic polynomial?

Back

A cubic polynomial is a polynomial of degree 3, which has the form ax³ + bx² + cx + d, where a, b, c, and d are constants. For example, 2x³ - 3x² + x - 5 is a cubic polynomial.

FLASHCARD QUESTION

Front

How do you add polynomials?

Back

To add polynomials, combine like terms by adding their coefficients. For example, (3x² + 2x + 1) + (2x² - 4x - 5) = 5x² - 2x - 4.

6.

FLASHCARD QUESTION

Front

How do you subtract polynomials?

Back

To subtract polynomials, distribute the negative sign and then combine like terms. For example, (4x² + x) - (x² + 2x) = 3x² - x.

FLASHCARD QUESTION

Front

What are like terms in polynomials?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x² and 5x² are like terms, while 3x² and 4x are not.
