coordinate

Question: The distance between the points $(am_{1}^{2},\,2a{{m}_{1}})$ and $(am_{2}^{2},\,2a{{m}_{2}})$ is

1) $a({{m}_{1}}-{{m}_{2}})\sqrt{{{({{m}_{1}}+{{m}_{2}})}^{2}}+4}$

2) $({{m}_{1}}-{{m}_{2}})\sqrt{{{({{m}_{1}}+{{m}_{2}})}^{2}}+4}$

3) $a({{m}_{1}}-{{m}_{2}})\sqrt{{{({{m}_{1}}+{{m}_{2}})}^{2}}-4}$

4) $({{m}_{1}}-{{m}_{2}})\sqrt{{{({{m}_{1}}+{{m}_{2}})}^{2}}-4}$
