Overview adding polynomials

The video tutorial explains how to add polynomials by combining like terms using two methods: the vertical method and the horizontal method. The vertical method involves writing polynomials one above the other and aligning like terms, while the horizontal method involves combining like terms directly. The tutorial provides examples and emphasizes the importance of keeping variable factors consistent.

What is the first step in the vertical method of adding polynomials?

• Add all coefficients together.

• Subtract the smaller polynomial from the larger one.

• Align the terms based on their variable factors.

• Align the terms based on their coefficients.

How do you handle a term in the vertical method that has no matching variable factor in the other polynomial?

• Ignore the term completely.

• Add a zero term for the missing factor.

• Subtract the term from the other polynomial.

• Multiply the term by zero.

What is the result of adding -4X^2 and 7X^2 using the vertical method?

• 0

• 3X^2

• -3X^2

• 11X^2

In the horizontal method, how are like terms combined?

• By adding their coefficients directly.

• By aligning them vertically.

• By subtracting the smaller coefficient from the larger one.

• By multiplying their coefficients.

Which method is suggested to reduce mistakes when adding polynomials?

• Multiplication method

• Subtraction method

• Horizontal method

• Vertical method
