Is the polynomial 3x2(x2 + 2x + 1) completely factored? if not, factor it. a. no; 3x2(x + 1)(x + 2) b. true c. no; 3x2(x + 1)(x − 1) d. no; 3x2 (x + 1)2

For this case we have the following polynomial:
 3x2 (x2 + 2x + 1)
 We observe that the polynomial is not completely factored.
 The expression in parentheses can be factored.
 We then have to rewrite:
 3x2 ((x + 1) (x + 1))
 3x ^ 2 (x + 1) ^ 2
 
 D.no; 3x2 (x + 1) 2

The correct answer would be the fourth choice

25 is obviously the correct answer
