We have the expression:
2x+4
Analyzing each term separately we have
2x=2*x
4=2*2
We can see there is one factor that both expressions have: the number 2
1. The GCF is 2
2.
The GCF is 2, and if we want to factor it out, we must divide both terms by 2:
2x+4=2(x+2)
Note the term 2x was divided by 2 to get x, and 4 by 2 is 2
The factored function is
2x+4=2(x+2)
