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.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part unchanged.

Front

What is the degree of a polynomial?

Back

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

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated as P = 2(length + width).

Front

Calculate the perimeter of a rectangle with width (2x + 3) and length (2x - 4).

Back

The perimeter is 8x - 2.

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

Back

The result is -4x + y + 6z.

What is the result of adding (4x^3 - 5x^2 + 3x) and (-2x^3 - x^2 + 6x)?

Back

The result is 2x^3 - 6x^2 + 9x.
