Distribute x2y: Distribute x2y across the terms inside the parentheses (2xy2−7xy+5x−4y). To distribute, multiply x2y by each term inside the parentheses.
Multiply 2xy2: Multiply x2y by the first term 2xy2.x2y×2xy2=2x3y3
Multiply −7xy: Multiply x2y by the second term −7xy.x2y×−7xy=−7x3y2
Multiply 5x: Multiply x2y by the third term 5x.x2y×5x=5x3y
Multiply −4y: Multiply x2y by the fourth term −4y.x2y×−4y=−4x2y2
Combine results: Combine the results from steps 2 to 5 to get the final expression. 2x3y3−7x3y2+5x3y−4x2y2
