A polynomial has two terms. Check all of the factoring methods that should be considered.

A represents London dispersion forces, which are weaker than the force represented by B.

Explanation:

London Dispersion Forces : Intermolecular forces exist  between non-polar molecules.  They are very weak forces.  Thought to be arise from the  motion of electrons.

H-bonding: It is a special type of dipole-dipole interaction  between the H-atom in a polar bond such as N-H,  O-H, F-H and an electronegative atom such as  nitrogen, oxygen and fluorine.

It is clear that H-bonding is stronger than London-dispersion.

So, the right choice is:

A represents London dispersion forces, which are weaker than the force represented by B.
