1)Find the LCM of m^2-4m-5 and m^2+8m+7. factorize both expressions you get (m+1)(m-5) and (m+1)(m+7) common factor is m+1 so LCM = (m+1)(m-5)(m+7) = m^3+3m^2-33m-35 2)Solve 8/(t+5)=(t-3)/(t+5)+(1/3). First convert the 1/3 to a fraction with (t+5) on the bottom and the other ...

List all the mulipltes for both number until you reacha number that is the same for both number. That will be your LCM. Example 12=12,24,36* 2=2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36*. As you can see 36 apperas on both 12 and 2 so the LCM is 36. Hope this helps!! K.C
