Answer:
Not sure what goes in the ( ) so best guess......
Step-by-step explanation:
5x^2+10x=5x
Move everything to one side:
=5x^2+10x+(-5x)
Combine like terms:
(5x^2)+(10x+(-5x))
Simplify:
5x^2+5x
It can either reduce or add to its value. Say that you had a number 5. If you move the place it would make it .5 which reduced its value to not even 1. But with the same 5. if you move the place the other way to 50. It increases its value significantly.
