Rules of Addition and Subtraction of like Terms In this lesson we will learn, how to add and subtract like terms Like Terms In an algebraic expression, like terms are terms that have same variables with same exponents and only the numerical coefficients of like terms are different. The terms must have the same variables […]

Zero degree polynomials are used to describe quantities that don’t change. 2. 1st degree polynomials are used to describe quantities that change at a steady rate. They are also used in many one-dimensional geometry problems involving length. 3. 2nd degree polynomials are used to describe quantities that change with some amount […]

Rule 1: In an expression, when all terms are positive, add their coefficients and variables and power of like terms remains the same. Add like terms examples in expressions: Example 1: Add like terms 2pq, 5pq, and […]
