If a and b are arbitrary distinct elements of a group G and H is any subgroup of G, then Ha=Hb⇔ab\power{-1}∈H aH=bH⇔b\power{-1}a∈H.
Let G be a group and let H be a normal subgroup of G. Prove that the factor group G/H is a group under the operation induced by the group operation of G. Hint: To prove that the factor group G/H is a group, you need to show that it satisfies the group axioms: closure, associativity, identity element, and inverse element. Remember to use the fact that H is a normal subgroup of G.
