Introduction

The concept of expanding and simplifying algebraic expressions is a fundamental aspect of mathematics, particularly in the realm of algebra. In this article, we will delve into the process of finding the product of a given algebraic expression, specifically the square of the binomial $(2a + b)$. We will explore the step-by-step process of expanding and simplifying this expression, and provide a comprehensive understanding of the underlying mathematical concepts.

Understanding the Expression

The given expression is $(2a + b)^2$, which represents the square of the binomial $2a + b$. To find the product of this expression, we need to apply the formula for expanding a squared binomial. This formula states that for any binomial $x + y$, the square of the binomial is given by $(x + y)^2 = x^2 + 2xy + y^2$.

Applying the Formula

To find the product of the given expression, we can apply the formula for expanding a squared binomial. We start by identifying the values of $x$ and $y$ in the binomial $2a + b$. In this case, $x = 2a$ and $y = b$. Now, we can substitute these values into the formula and expand the expression.

Expanding the Expression

Using the formula for expanding a squared binomial, we can write the expression as:

$$(2a + b)^2 = (2a)^2 + 2(2a)(b) + b^2$$

Simplifying the Expression

Now, we can simplify the expression by evaluating the terms. We start by squaring the first term, which gives us:

$$(2a)^2 = 4a^2$$

Next, we multiply the second term, which gives us:

$$2(2a)(b) = 4ab$$

Finally, we square the third term, which gives us:

$$b^2 = b^2$$

Combining the Terms

Now, we can combine the terms to get the final expression:

$$(2a + b)^2 = 4a^2 + 4ab + b^2$$

Conclusion

In this article, we have explored the process of finding the product of a given algebraic expression, specifically the square of the binomial $(2a + b)$. We have applied the formula for expanding a squared binomial and simplified the expression to get the final result. This process has provided a comprehensive understanding of the underlying mathematical concepts and has demonstrated the importance of algebraic manipulation in solving mathematical problems.

Additional Examples

To further illustrate the concept of expanding and simplifying algebraic expressions, let's consider a few additional examples.

Example 1: $(3x + 2y)^2$

Using the formula for expanding a squared binomial, we can write the expression as:

$$(3x + 2y)^2 = (3x)^2 + 2(3x)(2y) + (2y)^2$$

Simplifying the expression, we get:

$$(3x + 2y)^2 = 9x^2 + 12xy + 4y^2$$

Example 2: $(x - 2y)^2$

Using the formula for expanding a squared binomial, we can write the expression as:

$$(x - 2y)^2 = x^2 - 2(x)(2y) + (2y)^2$$

Simplifying the expression, we get:

$$(x - 2y)^2 = x^2 - 4xy + 4y^2$$

Final Thoughts

In conclusion, the process of expanding and simplifying algebraic expressions is a fundamental aspect of mathematics, particularly in the realm of algebra. By applying the formula for expanding a squared binomial and simplifying the expression, we can find the product of a given algebraic expression. This process has provided a comprehensive understanding of the underlying mathematical concepts and has demonstrated the importance of algebraic manipulation in solving mathematical problems.
