The correct Answer is:
To solve the problem, we need to analyze the given algebraic expression: \[ 3x^3 - 6x^2y + 4xy - 2x + y + 6x + x^2y + 9 \] We will identify the non-constant terms, find their numerical coefficients, and determine the coefficients of \( y \) in the terms that involve \( y \). ### Step 1: Identify Non-Constant Terms The non-constant terms in the expression are those that contain variables (either \( x \) or \( y \)). The constant term is \( 9 \). The non-constant terms are: 1. \( 3x^3 \) 2. \( -6x^2y \) 3. \( 4xy \) 4. \( -2x \) 5. \( y \) 6. \( 6x \) 7. \( x^2y \) ### Step 2: Find Numerical Coefficients Next, we will extract the numerical coefficients from each of the non-constant terms: 1. For \( 3x^3 \), the coefficient is **3**. 2. For \( -6x^2y \), the coefficient is **-6**. 3. For \( 4xy \), the coefficient is **4**. 4. For \( -2x \), the coefficient is **-2**. 5. For \( y \), the coefficient is **1** (since \( y \) can be written as \( 1y \)). 6. For \( 6x \), the coefficient is **6**. 7. For \( x^2y \), the coefficient is **1** (since \( x^2y \) can be written as \( 1x^2y \)). ### Step 3: List the Numerical Coefficients The numerical coefficients of the non-constant terms are: - \( 3, -6, 4, -2, 1, 6, 1 \) ### Step 4: Identify Coefficients of \( y \) Now, we will identify the coefficients of \( y \) in the terms that involve \( y \): 1. From \( -6x^2y \), the coefficient of \( y \) is **-6**. 2. From \( 4xy \), the coefficient of \( y \) is **4**. 3. From \( y \), the coefficient of \( y \) is **1**. 4. From \( x^2y \), the coefficient of \( y \) is **1**. ### Step 5: List the Coefficients of \( y \) The coefficients of \( y \) in the terms involving \( y \) are: - \( -6, 4, 1, 1 \) ### Final Answer - The numerical coefficients of the non-constant terms are: **3, -6, 4, -2, 1, 6, 1**. - The coefficients of \( y \) in the terms involving \( y \) are: **-6, 4, 1, 1**.
