Introduction

Simplifying complex algebraic expressions is a crucial skill in mathematics, particularly in algebra and calculus. It involves reducing an expression to its simplest form by combining like terms and canceling out common factors. In this article, we will focus on simplifying a given expression and identifying the incorrect parts of a quotient.

The Given Expression

The given expression is:

$$\frac{2 x^2 y - 5 x^2 y^2 + 4 x^3}{2 x^2 y}$$

This expression can be simplified by factoring out common terms and canceling out common factors.

Simplifying the Expression

To simplify the expression, we can start by factoring out the common term $2x^2y$ from the numerator:

$$\frac{2 x^2 y - 5 x^2 y^2 + 4 x^3}{2 x^2 y} = \frac{2 x^2 y(1 - 2.5y + 2x)}{2 x^2 y}$$

Now, we can cancel out the common factor $2x^2y$ from the numerator and denominator:

$$\frac{2 x^2 y(1 - 2.5y + 2x)}{2 x^2 y} = 1 - 2.5y + 2x$$

However, we can simplify the expression further by combining like terms:

$$1 - 2.5y + 2x = 2x - 2.5y + 1$$

Part A: Identifying the Incorrect Parts of Shawn's Quotient

Shawn needs to find the quotient of the given expression but divides incorrectly to get the answer. The incorrect quotient is:

$$x - 5y + 2xy$$

To identify the incorrect parts of Shawn's quotient, we need to compare it with the simplified expression:

$$2x - 2.5y + 1$$

By comparing the two expressions, we can see that the incorrect parts of Shawn's quotient are:

• The term $x$ is incorrect because it should be $2x$.
• The term $-5y$ is incorrect because it should be $-2.5y$.
• The term $2xy$ is incorrect because it is not present in the simplified expression.

Therefore, the correct quotient is:

$$2x - 2.5y + 1$$

Introduction

Simplifying complex algebraic expressions is a crucial skill in mathematics, particularly in algebra and calculus. In our previous article, we simplified a given expression and identified the incorrect parts of a quotient. In this article, we will provide a Q&A guide to help you understand the concepts and techniques involved in simplifying complex algebraic expressions.

Q&A

Q: What is the first step in simplifying a complex algebraic expression?

A: The first step in simplifying a complex algebraic expression is to factor out common terms. This involves identifying the common factors in the expression and grouping them together.

Q: How do I identify common factors in an expression?

A: To identify common factors in an expression, look for terms that have the same variable or constant factor. For example, in the expression $2x^2 + 4x^2$, the common factor is $2x^2$.

Q: What is the next step after factoring out common terms?

A: After factoring out common terms, the next step is to cancel out common factors. This involves dividing the expression by the common factor to simplify it.

Q: How do I cancel out common factors in an expression?

A: To cancel out common factors in an expression, divide the expression by the common factor. For example, in the expression $\frac{2x^2 + 4x^2}{2x^2}$, the common factor is $2x^2$. Canceling out the common factor gives us $1 + 2$.

Q: What is the final step in simplifying a complex algebraic expression?

A: The final step in simplifying a complex algebraic expression is to combine like terms. This involves adding or subtracting terms that have the same variable or constant factor.

Q: How do I combine like terms in an expression?

A: To combine like terms in an expression, add or subtract the coefficients of the terms. For example, in the expression $2x + 4x$, the like terms are $2x$ and $4x$. Combining the like terms gives us $6x$.
