Answer 1

Answer:

Step-by-step explanation:

1 cube is equal to 1 so

(x+1)(x+1)(x+1)/(x+1)

so it is (x+1)(x+1)

= x^2 + 1 or x square +1

please brainlist me

sorry I don't know how to type x square

Answer 2

Step-by-step explanation:

We have,

$\sf{\frac{x^{3}+1}{x+1}}$

$\sf{=\frac{(x+1)^{3}-3x(x+1)}{x+1}}$

$\sf{=\frac{(x+1)[(x+1)^{2}-3x]}{x+1}}$

$\sf{=(x+1)^{2}-3x}$

$\sf{=x^{2}+1+2x-3x}$

$\sf{=x^{2}-x+1}$

Therefore,

Remainder = 0

And Quotient $\bold{\sf{=x^{2}-x+1}}$
