The first step to factoring this expression would be finding the greatest common factor. Here, the two numbers we are analyzing are 20 and 16. The greatest common factor of both would be 4.
After identifying the GCF, the next step would be factoring this number out. So 20/4= 5 and 16/4=4. Therefore, the expression can be simplified as such:
4(5b-4)
Now the expression cannot be further simplified and this is your answer.
