Front

What are like terms?

Back

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

How do you add like terms?

Back

To add like terms, combine their coefficients. For example, 3x + 4x = (3 + 4)x = 7x.

How do you subtract like terms?

Back

To subtract like terms, subtract their coefficients. For example, 5x - 2x = (5 - 2)x = 3x.

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and exponents, combined using addition, subtraction, and multiplication. For example, 2x^2 + 3x - 5 is a polynomial.

Front

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 4x^3 + 2x^2 + 5, the degree is 3.
