Use a common denominator, m%5E2-4=%28m-2%29%28m%2B2%29
5%2F%28m%2B2%29+-+4%2F%28m-2%29+=+-20%2F%28m%5E2-4%29

%285%28m-2%29-4%28m%2B2%29%2B20%29%2F%28m%5E2-4%29=0
%285m-10-4m-8%2B20%29%2F%28m%5E2-4%29=0
%28m%2B2%29%2F%28%28m-2%29%28m%2B2%29%29=0
1%2F%28m-2%29=0

5/m+2 - 4/m-2 = -20/m^2-4
5(m-2)-4(m+2)=-20 Multiply each side by m^2-4.
5m-10-4m-8=-20
m=-2 This would cause division by zero, which is not allowed. The variable is undefined.
