Learn how to expand a binomial to fourth power by multiplying

The video tutorial explains the process of expanding binomials and trinomials using algebraic methods. It begins with an introduction to binomials and progresses to the concept of binomial squared. The instructor then introduces the box method for handling trinomials, emphasizing its organizational benefits. The tutorial concludes with a detailed application of the box method, demonstrating how to combine like terms to finalize the expression.

What is the expanded form of (X + Y)^2?

• X^2 + 4XY + Y^2

• X^2 + 2X + Y^2

• X^2 + XY + Y^2

• X^2 + 2XY + Y^2

Why is the box method useful in polynomial multiplication?

• It simplifies addition of terms.

• It helps in organizing terms and finding areas.

• It eliminates the need for multiplication.

• It is faster than other methods.

In the box method, what do the length and width represent?

• The degree of the polynomial

• The coefficients of the polynomial

• The sum of the polynomial

• The terms being multiplied

What is the expanded form of the polynomial using the box method?

• X^4 + 3X^3Y + 5X^2Y^2 + 3XY^3 + Y^4

• X^4 + 4X^3Y + 6X^2Y^2 + 4XY^3 + Y^4

• X^4 + 5X^3Y + 7X^2Y^2 + 5XY^3 + Y^4

• X^4 + 2X^3Y + 4X^2Y^2 + 2XY^3 + Y^4

How are like terms identified in the box method?
