To simplify the expression x² + 15x + 365x + 60, we first need to combine the like terms.
The terms 15x and 365x are both like terms as they both contain the variable x. We can add these terms together:
- 15x + 365x = 380x
So now, our expression looks like this:
x² + 380x + 60
This expression is now simplified as much as possible in its current form. There are no further like terms to combine and it does not factor using integers. Therefore, the final simplified expression is:
x² + 380x + 60
