Answer:
D)Factors are (x +1) ( x² +2) .
Step-by-step explanation:
Given : x³ + x² + 2x + 2.
To find : Use the grouping method to factor .
Solution : We have given x³ + x² + 2x + 2.
On taking common x² from first two term and 2 from last two terms.
x² ( x + 1) + 2( x +1).
On grouping.
(x +1) ( x² +2) .
Therefore, D )Factors are (x +1) ( x² +2) .
