Answer:

-6x⁷ + 12x − 3

Step-by-step explanation:

<u><em>Method 1</em></u> :

-3x^0\ (2x^7-4x+1)

= (-3x^0)\times 2x^7-(-3x^0)\times4x+(-3x^0)\times1

= (-3x^0)\times 2x^7+(3x^0)\times4x+(-3x^0)\times1

=-6x^{0+7}+12x^{0+1}-3x^0

=-6x^{7}+12x^{1}-3x^0

=-6x^{7}+12x-3

<u><em>Method 2</em></u> :

Note : x⁰ = 1

-3x^0\ (2x^7-4x+1)

=-3\ (2x^7-4x+1)

=-3\times2x^7-(-3)\times4x+(-3)\times1

=-6x^7+12x-3
