+6%2F%28m-5%29-2%2F%28m%2B5%29=8%2F%28m%5E2-25%29

+%286%28m%2B5%29-2%28m-5%29%29%2F%28%28m-5%29%28m%2B5%29%29=8%2F%28m%5E2-5%5E2%29

+%286m%2B30-2m%2B10%29%2F%28%28m-5%29%28m%2B5%29%29=8%2F%28%28m-5%29%28m%2B5%29%29


+%284m%2B40%29%2F%28%28m-5%29%28m%2B5%29%29=8%2F%28%28m-5%29%28m%2B5%29%29 ..if denominators same, numerators are same too, so we have
+4m%2B40=8
+4m=8-40
+4m=-32
+m=-32%2F4
+m=-8
