2xy(-3x+4y)-(x-2y)(2x^2-xy-3y^2) tolong dijawab ceffat ya kack

2xy ( -3x + 4y ) – ( x – 2y ) ( 2x² – xy – 3y² )

=> -6x²y + 8xy² – ( x – 2y ) ( 2x² – xy – 3y² )

=> -6x²y + 8xy² – 2x³ + 5x²y + xy² – 6y³

=> -2x³ – 6x²y + 5x²y + 8xy² + xy² – 6y³

=> -2x³ – x²y + 8xy² + xy² – 6y³

=> -2x³ – x²y + 9xy² + 6y³

Jadi, Jawaban adalah -2x³ -x²y + 9xy² + 6y³
