pleaseeeee answerrrrrrr fasttttttt pleaseeeee​

Answer 1

Answer:

${x}^{3} + {x}^{2} + x + 1$

is the answer.

Step-by-step explanation:

It's cuz ,

If we group them like ,

$( {x}^{3} + {x}^{2} ) + (x + 1)$

then in first one we can take x^2 as common and in second we can take 1 as common .

So our equation will look like this

${x}^{2} (x + 1) + 1(x + 1)$

And on taking x+1 as common our equation would look like

$(x + 1)( {x }^{2} + 1)$

And here we have x+1 as it's one of the factors
