Answer
$$15(2x - 3)$$
Work Step by Step
To factor this polynomial, we factor out the greatest common factor of $30x$ and $45$. This means we find the largest number that can go into both $30x$ and $45$ evenly. In this case, that number is $15$. If we divide both terms by $15$, we get:
$$15(2x - 3)$$
