-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
