L.C.M. Can someone please tell me if these are correct. Thank you

Ahh, thank you both then!!!!   

I think so .

You think?! Hmmm 

I still need help with this one

1). 12x ; 15x²  = 

Answer  = 60x² 

Factors are 4, 3, 5 and x^2   multiply them together......we get 60x^2

This one is correct

2). 2m; m2 – 4m + 4; 4m² – 8m 

Answer = 4m(m – 2)² 

2m,  m(m - 2) (m - 2), 4m(m - 2)

So ...  we need .... 4, m, and (m -2)^2  =

4m(m - 2)^2

And this one is correct, as welll !!!

Good job...!!
