Final answer:
The expression C³ + C² factorizes to C²(C + 1), as C² is the common factor between the two terms. Hence, answer option C) is correct.
Step-by-step explanation:
To factorize the expression C³ + C², we want to find common factors that we can take out. In this case, the common factor is C². We can factor out C² from both terms, giving us:
C³ + C² = C²(C + 1)
This is because each term in the original expression has at least a power of 2 of C, which allows us to factor it out. Thus, the expression C³ + C² factorizes to C²(C + 1), matching answer C).
