%283a+%2A+-7b+%2B+b%29+%2A+%28%28%28sqrt+%283%29%29%2F2%29%2A+a%5E2%2Ab%29

%28-21ab+%2B+b%29+%2A+%28%281.73%2F2%29%2A+a%5E2%2Ab%29
b%28-21a+%2B+1%29%2A+0.865%2A+a%5E2%2Ab%29
0.865a%5E2b%5E2%28-21a+%2B+1%29
now, if you set it equal to zero, you can calculate the values of a and b
0.865a%5E2b%5E2%28-21a+%2B+1%29=0
if 0.865a%5E2b%5E2=0 ...->...a=0 and b=0
if %28-21a+%2B+1%29=0 ...->...1=21a->...1%2F21=a
