Question

Find the LCM of 25y^2+100y and 5y^2+25y+20

Answer 1

25y^2+100y=25y(y+4)
5y^2+25y+20=(5y+5)(y+4)
so LCM=25y(y+4)(5y+5)

Answer 2

the answer was 25y(y+4)(y+1) this problem really stumps me....

Answer 3

25y^2+100y and 5y^2+25y+20
25y^2+100y = 25y(y+4)
5y^2+25y+20=5(y^2+5y+4)=5(y+4)(y+1)
To find the LCM, find the product of the factors, making sure common factors are not repeated, thus
LCM=25y(y+4)(y+1)
