Find the LCM:
z^414z^3+49z^2,3z^2147 and 5z+35

z^414z^3+49z^2
= z^2(z^2  14z+ 49)
= x^2(z7)^2
3z^2147
= 3(z^2  49)
= 3(z+7)(z7)
5z + 35
= 5(z+7)
LCM = 15z^2(z+7)(z7)^2

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?

Math
you know that 8x = 5y you know that 3y=14z since 5 = (5/3)*3, 5y = (5/3)*(3y) so, 5y = (5/3)(3y) = (5/3)(14z) = (70/3)z now you have 5y, which is the same as 8x. You want 12x. since 12 = (3/2)*8, 12x = (3/2)*8x. 12x = (3/2)(8x) = (3/2)(5y) …
