The correct Answer is:
To solve the problem of subtracting \(-2x^2y + 3xy^2\) from \(8x^2y\), we will follow these steps: ### Step 1: Write down the expression We start with the expression we need to subtract: \[ 8x^2y - (-2x^2y + 3xy^2) \] ### Step 2: Distribute the negative sign When we subtract the entire expression \(-2x^2y + 3xy^2\), we need to distribute the negative sign: \[ 8x^2y - (-2x^2y) - (3xy^2) \] This simplifies to: \[ 8x^2y + 2x^2y - 3xy^2 \] ### Step 3: Combine like terms Now, we combine the like terms. The like terms here are \(8x^2y\) and \(2x^2y\): \[ (8x^2y + 2x^2y) - 3xy^2 \] This gives us: \[ 10x^2y - 3xy^2 \] ### Final Answer Thus, the result of subtracting \(-2x^2y + 3xy^2\) from \(8x^2y\) is: \[ 10x^2y - 3xy^2 \] ---
