Question

Factor

Answer 1

4y - 20.......u need to find a common factor that can go into 4y and 20.....the only common factor is 4. So u can factor that out.....4 goes into 4 one time (but do not forget the y) and 4 goes into 20 five times....4(y - 5)

4(y - 5)...u can also check ur answer by distributing the 4 through the parenthesis and getting 4 * y - 4 * 5 = 4y - 20

Answer 2

Well you just find the greatest common factor of 4 and 20 which is 4 and then you divide each number by the gcf and you get 4(y-5)
