Brainlies asap! create a factorable polynomial with a gcf of 3x. rewrite that polynomial in two other equivalent forms. explain how each form was created.

We are asked to create a factorable polynomial that has a GCF of 3x. This can be done in many different ways, but we'll use the easiest one. This will be completing the square. 
GCF: 3x
Suitable Polynomial: 3x³ + 18x² +27x
Other Expressible Ways:
1) 3x(x² + 6x + 9)
2) 3x(x + 3)²
We got this by creating a perfect trinomial, which is x² + 6x + 9, as it can be factored into the binomial (x + 3)². All we had to do is multiply 3x to x² + 6x + 9 and simplify. Hope this helped!
