Adding two polynomials with multiple terms

The video tutorial introduces the concept of vertical addition, initially using simple numbers like 14 + 21, and then extends the concept to algebraic expressions. The teacher emphasizes the importance of aligning like terms vertically to simplify the addition process. The tutorial includes examples and practice exercises to reinforce the learning, ensuring students understand how to apply vertical addition to both basic arithmetic and algebraic terms.

What is the benefit of writing addition problems vertically instead of horizontally?

• It makes the numbers look bigger.

• It allows for easier alignment of digits.

• It is a more traditional method.

• It requires less paper.

Why is it important to align like terms when adding polynomials?

• To make the expression longer.

• To make the expression look neat.

• To avoid using a calculator.

• To ensure correct addition of coefficients.

Which of the following is a like term to 5X^3?

• 6X^2

• 5X

• 3X^3

• 4

What is the result of adding 3X^3 and 5X^3?

• 3X^6

• 5X^6

• 8X^3

• 15X^3

What is the sum of 2X^2 and -4X^2?

• -2X^2

• 6X^2

• -6X^2

• 2X^2
