The correct Answer is:
To find the product of the algebraic expressions \( (3m - 4n) \) and \( (2m - 3n) \), we will use the distributive property (also known as the FOIL method for binomials). Here’s a step-by-step solution: ### Step 1: Write down the expression We start with the expression: \[ (3m - 4n)(2m - 3n) \] ### Step 2: Distribute the first term of the first expression Multiply \( 3m \) by each term in the second expression: \[ 3m \cdot 2m = 6m^2 \] \[ 3m \cdot (-3n) = -9mn \] ### Step 3: Distribute the second term of the first expression Now, multiply \( -4n \) by each term in the second expression: \[ -4n \cdot 2m = -8mn \] \[ -4n \cdot (-3n) = 12n^2 \] ### Step 4: Combine all the products Now, we combine all the results from the previous steps: \[ 6m^2 - 9mn - 8mn + 12n^2 \] ### Step 5: Combine like terms Combine the like terms \( -9mn \) and \( -8mn \): \[ 6m^2 - 17mn + 12n^2 \] ### Final Answer Thus, the product of the expressions is: \[ 6m^2 - 17mn + 12n^2 \] ---
