Question

-3x° (2x7 - 4x + 1) multiply through polynomial

Answer 1

-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`
