Answer:

Step-by-step explanation:
Considering the equation

Solving


As





![=\left(x+1\right)\frac{x^4+8x^3+8x^2+8x+7}{x+1}...[A]](https://tex.z-dn.net/?f=%3D%5Cleft%28x%2B1%5Cright%29%5Cfrac%7Bx%5E4%2B8x%5E3%2B8x%5E2%2B8x%2B7%7D%7Bx%2B1%7D...%5BA%5D)
Solving


Putting
=
in equation [A]
So,
![\left(x+1\right)\frac{x^4+8x^3+8x^2+8x+7}{x+1}...[A]](https://tex.z-dn.net/?f=%5Cleft%28x%2B1%5Cright%29%5Cfrac%7Bx%5E4%2B8x%5E3%2B8x%5E2%2B8x%2B7%7D%7Bx%2B1%7D...%5BA%5D)

As

So,
Equation [A] becomes

So, the polynomial equation becomes
