Adding two polynomials

The video tutorial explains how to subtract two polynomials by aligning like terms and ensuring that the subtraction is applied to each term in the second polynomial. It highlights common mistakes, such as not applying the negative sign to all terms, and provides a step-by-step approach to correctly subtract polynomials.

What is the first step in subtracting two polynomials?

• Add the polynomials

• Multiply the polynomials

• Identify and align like terms

• Divide the polynomials

What common mistake do students make when subtracting polynomials?

• Forgetting to multiply terms

• Not distributing the negative sign across all terms

• Adding instead of subtracting

• Ignoring the coefficients

When subtracting polynomials, what should you do with the negative sign?

• Use it to multiply the polynomials

• Distribute it to each term in the second polynomial

• Apply it only to the first term

• Ignore it

How do you ensure accuracy when subtracting polynomials?

• By multiplying the polynomials

• By ignoring the coefficients

• By adding all terms together

• By aligning like terms and carefully subtracting
