10x+40
10x=2 times5 x
40=2times 2 times 2 times 5
cancel out twos
2(5x+20)

OK just like factoring a number:
10x +40
|
10 (x +4)
|
2-5-(x+4)
Factors are 2, 5 , (x+4)
2*5*(x+4)
Hope that helps.

the GCF (greatest common factor) of
10 and 40 is 10
so 10x+40 becomes 10*x + 10*4
which becomes 10(x + 4)

factor out the greatest common factor
in this case 10 is the greatest common factor of 10 and 40 so.....
10(x + 4)

1. you can make it a little easier by taking 10 out of the problem and make the statement look like 10(x+4)
