Question

Help, I am totally confused on this problem..Find the LCM (4+7t),(16-49t^(2)),(4-7t)

Answer 1

16-49t^2 = (4+7t)(4-7t).

So, LCM must be 16-49t^2.

Answer 2

than you...how did you figure that out, I am confused on how to get it..

Answer 3

LCM is the least common multiple. The other two terms given are factors of 16-49t^2. So, the "common" multiple has to be this term. It is least because there is no other factor but just the three.

Answer 4

oh ok...i see what you did, thanks again GT..
