(10) \( 7-2 m x n \) State the coefficient of the term indicated: (1) \( -3 x^{2}+4 x-3 \) (2) \( -3 x^{2}+4 x-3 \) (the term in \( x \) ) (2) \( (a+b) x^{3}-x^{2} y+x-1 \) (the term in \( x^{2} \) ) (the term in \( x^{3}, x^{2} \)

Let's break down the problem step by step to find the coefficients of the specified terms in the given expressions. ### Expression 1: \( -3x^{2} + 4x - 3 \) 1. **Identify the term in \( x \)**: - The term in \( x \) is \( 4x \). 2. **Coefficient of the term in \( x \)**: - The coefficient is \( 4 \). ### Expression 2: \( (a+b)x^{3} - x^{2}y + x - 1 \) 1. **Identify the term in \( x^{2} \)**: - The term in \( x^{2} \) is \( -x^{2}y \). 2. **Coefficient of the term in \( x^{2} \)**: - The coefficient is \( -y \). 3. **Identify the term in \( x^{3} \)**: - The term in \( x^{3} \) is \( (a+b)x^{3} \). 4. **Coefficient of the term in \( x^{3} \)**: - The coefficient is \( a + b \). ### Summary of Coefficients: 1. Coefficient of \( x \) in \( -3x^{2} + 4x - 3 \) is \( 4 \). 2. Coefficient of \( x^{2} \) in \( (a+b)x^{3} - x^{2}y + x - 1 \) is \( -y \). 3. Coefficient of \( x^{3} \) in \( (a+b)x^{3} - x^{2}y + x - 1 \) is \( a + b \).
