Question

x^4-16;x+2 Using long division method check whether the second polynomial is a factor of the first polynomials
​

Answer 1

Step-by-step explanation:

given polynomials are :

x^4-16

x+2

x+2)x^4-16 ( x^3 - 2x^2 + 4x - 8 = quotient

x^4+2x ^3

- -

__________

-2x^3-16

-2x^3-4x^2

+ +

_____________

+4x^2-16

+4x^2+8x

- -

__________

-8x -16

-8x - 16

+ +

________

0 = remainder

__________

so, the second polynomial is a factor of the first polynomials
