Introduction

In algebra, simplifying expressions is a crucial step in solving equations and inequalities. It involves combining like terms and eliminating any unnecessary components. In this article, we will focus on performing algebraic operations to simplify the given expression: $\left(4x^2 - 8\right) + \left(2x^2 - 8x\right)$. We will break down the process step by step, using various mathematical techniques to arrive at the final simplified expression.

Understanding the Expression

The given expression is a combination of two separate expressions: $\left(4x^2 - 8\right)$ and $\left(2x^2 - 8x\right)$. To simplify this expression, we need to combine like terms and eliminate any unnecessary components.

Like Terms

Like terms are terms that have the same variable raised to the same power. In this expression, we have two like terms: $4x^2$ and $2x^2$. We can combine these terms by adding their coefficients.

Combining Like Terms

To combine like terms, we add their coefficients. In this case, we have:

$$\left(4x^2 - 8\right) + \left(2x^2 - 8x\right) = \left(4x^2 + 2x^2\right) - 8 - 8x$$

Now, we can simplify the expression by combining the like terms:

$$\left(4x^2 + 2x^2\right) - 8 - 8x = 6x^2 - 8 - 8x$$

Eliminating Unnecessary Components

In this expression, we have a constant term $-8$ that is not necessary. We can eliminate this term by subtracting it from the expression:

$$6x^2 - 8 - 8x = 6x^2 - 8x - 8$$

Final Simplified Expression

The final simplified expression is:

$$6x^2 - 8x - 8$$

This expression is the result of combining like terms and eliminating unnecessary components.

Conclusion

In this article, we performed algebraic operations to simplify the given expression: $\left(4x^2 - 8\right) + \left(2x^2 - 8x\right)$. We combined like terms, eliminated unnecessary components, and arrived at the final simplified expression: $6x^2 - 8x - 8$. This expression is a result of careful analysis and simplification of the original expression.
