What are like terms and why do they have to be the same to combine

The video tutorial explains the concept of combining like terms in algebra, starting with simple numbers and moving on to variables and exponents. It emphasizes the importance of understanding that only terms with the same factors can be combined. The tutorial uses examples like apples and sticks to illustrate the concept of like terms and explains why terms with different variables or exponents cannot be combined. The video also discusses the factors of terms and how they determine whether terms can be combined.

Why can't 3X + 2Y be combined into a single term?

• They have the same coefficients

• They represent different variables

• They are both Y terms

• They are both X terms

Why can't 3X and 2X^2 be combined?

• They are both linear terms
