What is a polynomial?

Back

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

What does it mean to add polynomials?

Back

Adding polynomials involves combining like terms from two or more polynomial expressions to form a new polynomial.

Front

What are like terms in polynomials?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part the same. For example, 3x + 5x = 8x.

What is the sum of (-3x + 4) + (8x - 5)?

Back

5x - 1.

What is the sum of (2x + 5y - z) + (-6x - 4y + 7z)?

Back

-4x + y + 6z.

What is the sum of (x³ - 2x² + 3) + (2x³ + 3x² - 1)?

Back

3x³ + x² + 2.

What is the sum of (3y² + y³ - 5) + (4y² - 4y + 2y³ + 8)?

Back

3y³ + 7y² - 4y + 3.

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 4x² + 3x + 1, the degree is 2.

What is a coefficient in a polynomial?

Back

A coefficient is a numerical factor in a term of a polynomial. For example, in 5x², 5 is the coefficient.
