How to subtract two large polynomials by rewriting as an addition problem

The video tutorial explains how to simplify subtraction problems by rewriting them as addition problems. The teacher demonstrates distributing negative signs to each term, making subtraction easier. The importance of arranging terms in descending order and using the vertical method for addition is emphasized. The tutorial concludes with a final example, showing the complete process and the final answer.

What is the initial step suggested by the teacher to simplify subtraction problems?

• Convert subtraction into multiplication

• Rewrite subtraction as an addition problem

• Use a calculator

• Ignore the negative sign

Why is it important to arrange terms in descending order before using the vertical method?

• To make the problem look neat

• To make subtraction easier

• To ensure like terms are aligned for addition

• To confuse the students

What does the teacher suggest doing with the negative sign in subtraction problems?

• Ignore it

• Use it only for constants

• Distribute it to each term

• Convert it to a positive sign

What is the key to successfully adding terms vertically?

• Ignoring the coefficients

• Starting with the smallest term

• Using a calculator

• Aligning like terms together

What is the final answer obtained after performing the addition?

• Ten X^3 - 5 X squared + 5 X - 6

• Ten X^3 + 5 X squared - 5 X + 6

• Fifteen X^3 + 5 X squared - 5 X + 6

• Fifteen X^3 - 5 X squared + 5 X - 6
