I'll give you an idea on how to do these. Let me know if this helps.

To find the LCM, first find the GCF (greatest common factor) between the two polynomials. Once you have the GCF, multiply the two polynomials together and then divide by the GCF. That result will be the LCM.

Example: To find the LCM of and , take note that the GCF is 1 (ie they have no common factor). So the LCM is
