(4x+3) (2x-1)= (3x-1) (2x-1)= (2x-5) (2x+5)= (3x-y) (3y+y)= (x+3) (2x-y-5)= (2x+3)²= (3x-2y)²= tolong di Jawab yaa...

1. ( 4x + 3 ) ( 2x - 1 ) = 8x² + 2x - 3
2. ( 3x - 1 ) ( 2x - 1 ) = 6x² - 5x + 1
3. ( 2x - 5 ) ( 2x + 5 ) = 4x² - 25
4. ( 3x - y ) ( 3x + y ) = 9x² - y²
5. ( x + 3 ) ( 2x - y - 5 ) = 2x² - xy + x - 3y - 15
6. ( 2x + 3 )² = 4x² + 12x + 9
7. ( 3x - 2y )² = 9x² - 12xy + 4y²

semoga membantu :)
