Still there?
OpenStudy (anonymous):
Not sure what to do with the second two, but the first one is as follows:
OpenStudy (anonymous):
\[x^2+10x ; x(x+10)\]

Just plug in the minus for the second part
OpenStudy (anonymous):
@kashbmaryd still here
OpenStudy (anonymous):
@kashbmaryd what is the LCD though?
OpenStudy (anonymous):
sorry LCM
OpenStudy (anonymous):
\[
\text{LCM}(a,b) = \frac{a\cdot b}{GCF(a,b)}
\]

@wio in my equation though what would a & b be?
OpenStudy (anonymous):
the things which you want to find the LCM of.
OpenStudy (anonymous):
I'm still lost. The GCF is x , but not sure what the least is
OpenStudy (anonymous):
What two expression are you trying to find the LCM of?

okay \[
\text{LCM}(x^2+10x,x^2) = \frac{(x^2+10x)(x^2)}{GCF(x^2+10x,x^2)} = \frac{(x^2+10x)(x^2)}{x} = (x^2+10x)x = x^3+10x^2
\]
OpenStudy (anonymous):
\[\begin{split}
\text{LCM}(x^2+10x,x^2) &= \frac{(x^2+10x)(x^2)}{GCF(x^2+10x,x^2)} \\
&= \frac{(x^2+10x)(x^2)}{x} \\
&= (x^2+10x)x\\
&= x^3+10x^2
\end{split}\]
OpenStudy (anonymous):
so the LCM is x^2 + 10x^2?
OpenStudy (anonymous):
look again.
OpenStudy (anonymous):
-10?
