Answer:

-6x⁷ + 12x − 3

Explanation:

Method 1 :


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


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


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


=-6x^(0+7)+12x^(0+1)-3x^0


=-6x^(7)+12x^(1)-3x^0


=-6x^(7)+12x-3

Method 2 :

Note : x⁰ = 1


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


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


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


=-6x^7+12x-3
