Question

Find the LCM of each set of polynomials. If needed, show work and explain.
18. 4w - 12, 2w - 6

Answer 1

\[
LCD(a,b) = \frac{a\times b}{GCD(a,b)}
\]

Answer 2

Since \(4w-12 = (2)(2w-6)\), we know the GCF is \(2w-6\) \[\begin{split}
LCM(4w-12,2w-6) &= \frac{(4w-12)(2w-6)}{GCF(4w-12,2w-6)}\\
&= \frac{(4w-12)(2w-6)}{2w-6} \\&= 4w-12
\end{split}\]

What's the answer @satellite73 and @Mertsj

Answer 4

Factor each one and take the largest power of every DIFFERENT factor. That is the LCM
