v^3+10v^2+25v,x^2-10v

Question

anonymous · Answer

are these two problems?

anonymous · Answer

I do not believe so, it asks me to find the LCM

anonymous · Answer

why is there a comma between 25v and x^2?

The lowest common multiplier is "v"

$$v(v^2+10v+25x^2-10)$$

anonymous · Answer

I am not sure, the problems looks like this,

anonymous · Answer

that's a v not an x.
The LCM is the least common multiplier of the two equations.

$$v^3+10v^2+25v , v^2-10v$$

Between those two equations, what terms do they have in common with each other.  In other words, what can be stripped from both equations?

anonymous · Answer

the v^2

anonymous · Answer

that leaves me with the -10v, where does that go?

anonymous · Answer

25v only has one v.  Try factoring the first equation into a difference of squares
and see if the common factor can be factored into the second equation?

Hint:
$$v^3+10v^2+25v = v[(v+5)(v+5)]$$
