Answer:
3×(×+5)
Step-by-step explanation:
get the gcf (greatest common factor) or similarity of 3x² and 15x
first, 3 and 15
- they can be divided by 3, so 3 is their gcf or similarity
next, x² and x
- they can be divided by x, so x is their gcf or similarity
- it cannot be x² because "x" in 15x has only one x
Overall, the gcf is 3x
so divide 3x to each variable 3x^2 and 15x
3x((3x²)/3x + 15x/3x)
do a cancellation, you'll get
3x(x+5)
