Question

Quizplus · Accepted Answer

The given expression is a perfect square trinomial since it can be rewritten as $(c+3)^2$. Therefore, the correct factorization is $(c+3)(c+3)$ or $(c+3)^2$. Option C matches this factorization.

Factor c2+6c+9c ^ { 2 } + 6 c + 9c2+6c+9

Factor $c ^ { 2 } + 6 c + 9$
