find the LCM of y^2+6y+9 and y^2+y6

Algebra 
h8er_for_h8er
y^3+6y^2+9y=Y*(Y^2+6Y+9)=Y*(Y+3)^2
y^26y=Y*(Y6)
The unique factors are therefore Y, (Y+3)^2 & (Y6)
Y*(Y+3)^2*(Y6) is the lcm 
Algebra 
Reiny
y^2 + 6y + 9
= (y+3)^2
y^2 + y  6
= (y+3)(y2)
so LCM = (y2)(y+3)^2

I have the answer and would love confirmation. VERY APPRECIATED! Find the LCM OF (1+2t), (14t^2), and (12t). 14t^2=(1+2t)(12t) 1+2t = 1+2t 14t^2= (1+2t)(12t) 12t = 1  2t. The LCM for all numbers is 14t^2 = (1+2t)(12t) Thank …

I am stumped by these two LCM questions for some reason. Find The LCM for #1 2(R7) and 14(R7) #2 (1+4r), (116r^2), and (14r) It seems like #1 is already at the LCM and #2 would be (1+4r)(14r) Am I even vaguely correct?
