Answer:
5(x+1)
Explanation:
So factor is to make it simplified like x(y+c) {I made up random variable for an example but almost all factored problems look like this}
So first find the Greatest Common Factor or GCF for short
The GCF between 5x and 5 is 5
So you divide the whole thing by 5
5x+5/5
you’d get x+1
Now for the 5 just put it around X+1 but with parenthesis
5(x+1)
