Jawaban:
(6x² + 5x³)(7x⁴ - 3x⁵) = 42x⁶ - 17x⁷ - 15x⁸
Penjelasan dengan langkah-langkah:
(6x² × 7x⁴) = (6×7)x^(⁴+²) = 42x⁶
(6x² × 3x⁵) = (6×3)x^(⁵+²) = 18x⁷
(5x³ × 7x⁴) = (5×7)x^(³+⁴) = 35x⁷
(5x³ × 3x⁵) = (5×3)x^(³+⁵) = 15x⁸
» Gabungkan:
42x⁶ - 18x⁷ + 35x⁷ - 15x⁸
= 42x⁶ - ( 18x⁷ + 35x⁷ ) - 15x⁸
= 42x⁶ - 17x⁷ - 15x⁸
