Penjelasan dengan langkah-langkah:
= 2x(x + 4) - 3(x + 4)
= 2x² + 8x - 3x - 12
= 2x² + 5x - 12
__
= 3m(3m - 2n) + 2n(3m - 2n)
= 9m² - 6mn + 6nm - 4n²
Jawaban:
(2x - 3)(x + 4)
2x(x - 4) - 3(x + 4)
2x² - 8x - 3x + 12
2x² - 5x + 12
(3m + 2n)(3m - 2n)
3m(3m + 2n) + 2n(3m - 2n)
9m² + 6mn + 6nm - 4n²
semoga membantu
