Adding three polynomials

The video tutorial explains how to add three polynomials by first removing unnecessary grouping symbols and then combining like terms. The instructor emphasizes the importance of identifying terms with the same base and exponent to combine them effectively. The process involves rewriting the polynomial to group like terms together and then performing arithmetic operations to simplify the expression. The tutorial concludes with a demonstration of the final combined polynomial.

What is the first step in simplifying the addition of polynomials?

• Combine like terms

• Remove grouping symbols

• Multiply the polynomials

• Divide the polynomials

When combining like terms, what must be the same for the terms to be combined?

• The coefficients

• The exponents and variables

• The number of terms

• The polynomial degree

Which of the following terms can be combined with -8X^4?

• -5XY

• -5X^2

• -5X^4

What is the result of combining -12X^3Y, -14X^3Y, and -4X^3Y?

• -32X^3Y

• -28X^3Y

• -26X^3Y

• -30X^3Y

What is the final result of combining 4XY^3 and -7XY^3?

• 11XY^3

• 3XY^3

• -11XY^3

• -3XY^3
