In this task, we are asked to multiply binomials using the FOIL method, which stands for First, Outer, Inner, Last. The process involves multiplying each term in the first binomial by each term in the second binomial to obtain a quadratic expression. The specific example provided appears to be "24532x4x5," which seems to be a sequence of numbers rather than a clear binomial expression. For clarity and academic accuracy, we will interpret similar binomial multiplication as the primary focus because the instructions specify multiplying binomials using FOIL.
To demonstrate the application of FOIL, consider the example (2x + 3)(6x + 9). Using the FOIL method, we multiply each term in the first binomial by each in the second:
First: 2x * 6x = 12x2
Outer: 2x * 9 = 18x
Inner: 3 * 6x = 18x
Last: 3 * 9 = 27
Next, sum the products: 12x2 + 18x + 18x + 27 = 12x2 + 36x + 27. This is the expanded form of the binomials after applying FOIL and combining like terms.

Multiplying binomials is a fundamental algebraic skill that relies on systematic expansion techniques such as the FOIL method. FOIL, an acronym for First, Outer, Inner, Last, guides students through the process of distributing each term in one binomial with each term in the other binomial. When properly executed, FOIL ensures that all terms are accounted for, and the resulting expression can be simplified by combining like terms.
The importance of mastering binomial multiplication extends beyond basic algebra; it forms the foundation for understanding quadratic expressions, factoring, and polynomial algebra. By exemplifying the process through specific cases, such as (2x + 3)(6x + 9), students develop problem-solving fluency and the ability to manage more complex algebraic expressions.
An interesting aspect of binomial multiplication relates to special products, notably the difference of squares, perfect square trinomials, and the sum and difference identities. Recognizing these forms simplifies calculations significantly. For instance, the product of conjugates like (3x + 7)(3x - 7) directly yields a difference of squares: 9x2 - 49, eliminating the need for full expansion.
Similarly, squares of binomials such as (2x - 6y)(2x + 6y) utilize the difference of squares formula to produce 4x2 - 36y2. These shortcuts are invaluable in algebraic manipulation, especially when simplifying expressions or solving equations.
Furthermore, the multiplication of binomials leading to quadratic expressions can be viewed as the algebraic interpretation of area models. Each term represents dimensions of rectangles, and expansion models the total area when the rectangles are combined. This visual perspective enhances understanding and helps students connect algebraic operations to geometric interpretations.
In addition to product expansions, combining polynomials requires distributing negative signs through subtractions and then combining like terms efficiently. For example, adding (2x2 - 4x + 3) and (5x2 - 6x + 1), and subtracting (x2 - 9x + 8), results in (2x2 - 4x + 3) + (5x2 - 6x + 1) - (x2 - 9x + 8). Carefully distributing the negative and consolidating similar terms yields the combined expression: (6x2 - x - 4).
Understanding these algebraic operations provides essential tools for analyzing more complex functions, solving quadratic equations, and tackling word problems involving area, profit, and probability. The capacity to recognize patterns such as the difference of squares, perfect squares, and factorizations simplifies many calculations, making algebra a powerful tool in mathematics and its applications.
