Hi New Here and new to the college math. I have started back to school after 43 yrs and this is like a foreign language to me so I am hoping I can get an explaination I can understand and use.

Subtract:

_____1_____ minus ____x+4______

x^2 - 16 minus x^2 - 3x - 4

Thank you for your time. Can't figure out how to type this problem out better so I hope you get the gist of it.
