Introduction

In mathematics, simplifying expressions is a crucial skill that helps in solving various problems in algebra, geometry, and other branches of mathematics. One of the most common expressions that require simplification is the square of a binomial, which is a polynomial of the form ${(a + b)^2}$ . In this article, we will focus on simplifying the expression ${$ (3x + 4y)^2$}$, which is a binomial raised to the power of 2.

Understanding the Concept of Binomial Squaring

Before we dive into simplifying the expression, let's understand the concept of binomial squaring. When we square a binomial, we get a trinomial, which is a polynomial with three terms. The general form of a binomial squared is ${(a + b)^2 = a^2 + 2ab + b^2}$ . This formula can be applied to any binomial, and it helps in simplifying expressions quickly.

Applying the Binomial Squaring Formula

Now, let's apply the binomial squaring formula to the expression ${$ (3x + 4y)^2$}$. We can see that the binomial is of the form ${(3x + 4y)}$ , where ${a = 3x}$ and ${b = 4y}$ . Using the formula, we get:

${(3x + 4y)^2 = (3x)^2 + 2(3x)(4y) + (4y)^2}$

Simplifying the Expression

Now, let's simplify the expression by evaluating the terms:

${(3x)^2 = 9x^2}$

${(4y)^2 = 16y^2}$

The middle term, ${2(3x)(4y)}$ , can be simplified as follows:

${2(3x)(4y) = 24xy}$

Combining the Terms

Now, let's combine the terms to get the final simplified expression:

${(3x + 4y)^2 = 9x^2 + 24xy + 16y^2}$

Conclusion

In this article, we simplified the expression ${$ (3x + 4y)^2$}$ using the binomial squaring formula. We applied the formula to the given binomial and simplified the resulting trinomial. The final simplified expression is ${9x^2 + 24xy + 16y^2}$ . This expression can be used in various mathematical problems, such as solving quadratic equations and finding the area of a triangle.

Real-World Applications

The expression ${$ (3x + 4y)^2$}$ has several real-world applications in mathematics and science. For example, it can be used to find the area of a triangle with vertices at ${(x_1, y_1)}$ , ${(x_2, y_2)}$ , and ${(x_3, y_3)}$ . The formula for the area of a triangle is given by:

${A = \frac{1}{2} |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|}$

This formula can be simplified using the expression ${$ (3x + 4y)^2$}$.
