Find The Square And Simplify Your Answer.$\[(4k + 2)^2\\]$\[\square\\]

Introduction

In algebra, squaring a binomial expression is a fundamental concept that helps us simplify complex expressions. In this article, we will focus on finding the square of the binomial expression $(4k + 2)^2$ and simplify our answer. We will break down the process into manageable steps, making it easy to understand and apply.

Understanding the Binomial Expression

A binomial expression is a polynomial with two terms. In this case, the binomial expression is $(4k + 2)$. To square this expression, we need to multiply it by itself.

Squaring the Binomial Expression

To square the binomial expression, we will use the formula $(a + b)^2 = a^2 + 2ab + b^2$. In this case, $a = 4k$ and $b = 2$.

Step 1: Square the First Term

The first term is $4k$. To square this term, we need to multiply it by itself.

$$(4k)^2 = 16k^2$$

Step 2: Square the Second Term

The second term is $2$. To square this term, we need to multiply it by itself.

$$(2)^2 = 4$$

Step 3: Multiply the Two Terms

Now, we need to multiply the two terms together. We will use the distributive property to multiply $4k$ by $2$.

$$4k \cdot 2 = 8k$$

Step 4: Combine the Terms

Now, we need to combine the terms we have squared and multiplied. We will use the formula $(a + b)^2 = a^2 + 2ab + b^2$ to combine the terms.

$$(4k + 2)^2 = 16k^2 + 8k + 4$$

Simplifying the Answer

Now that we have squared the binomial expression, we can simplify our answer. We can rewrite the expression as a single fraction.

$$(4k + 2)^2 = \frac{16k^2 + 8k + 4}{1}$$

Conclusion

Squaring a binomial expression is a fundamental concept in algebra that helps us simplify complex expressions. In this article, we have focused on finding the square of the binomial expression $(4k + 2)^2$ and simplifying our answer. We have broken down the process into manageable steps, making it easy to understand and apply.
