TERIMA KASIH :D

Answer 1

1. (X²+2y-4)+(4y+8-3x²)= -3x²+x²+2y+4y-4+8= -2x²+6y+4 2. (X²+2y-4)-(4y+8-3x²)= x²+2y-4-4y-8+3x²=3x²+x²+2y-4y-4-8= 4x²-2y-12 3. 2(5a-b)= 10a-2b 4. (2a+3)²= (2a+3)(2a+3)= 4a²+6a+6a+9= 4a²+12a+9 5. 3a(2a-b+4)= 6a²-3ab+12a 6. (-5x+y)(x²-y+3)= -5x³+5xy-15x+x²y-y²+3y Semoga membantu
