Answer:
-10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
Step-by-step explanation:
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
= -10x⁶ + 4x⁴ - 8x³ + 20x⁵ - 8x³ + 16x² - 30x³ + 12x - 24
= -10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
Is same as
(2x³ - 4x² + 6)(-5x³ + 2x - 4)
Because multiplication is commutative.
a×b = b×a
