Penjelasan dengan langkah-langkah:
= 3x(2x² + x - 4) + (4x(2x² - 2x + 2))
= 3x(2x² + x - 4) + 4x(2x² - 2x + 2)
= 6x³ + 3x² - 12x + 8x³ - 8x² + 8x
= 6x³ + 8x³ + 3x² - 8x² - 12x + 8x
= 14x³ - 5x² - 4x
3x(2x² + x - 4) + 4x(2x² - 2x + 2)
= (3x(2x²) + (3x(x) - (3(4) + (4x(2x²) - (4x(x) + (4(2)
= 6x³ + 3x² - 12 + 8x³ - 8x² + 8
= (6 + 8)x³ + (3 - 8)x² - (12x - 8)x
= 14x² + (-5)x² - 4x
