Which of the following is a factor of 3x3 + 18x2 + 27x?

9x

x3

x + 3

x - 3

I hope this helps you

3x (x^2+6x+9)

3x (x+3). (x+3)

3x. (x+3)^2

So based on the given expression above, that factor of 3x3 + 18x2 + 27x would be x + 3. So the answer is the third option. So how did we get x + 3. Firstly, we factor the given expression by 3x. So, it would look like this.
3x (x+3)(x+3). Hope this is the answer that you are looking for. 

The answer is the numbers between =5 and 5
