Question 864856
{{{1/b + 1/b - 4 = b - 3/b - 4}}}
Multiply both sides by b
{{{2-4b=b^2-3-4b}}}
Add 4b-2 to both sides
{{{b^2-5=0}}}
Plug the values into the quadratic formula
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{x = (+-sqrt(-4*1*-5 ))/(2*1) }}}
{{{x =(+-sqrt(20))/2}}}
{{{x =(sqrt(20))/2}}} OR {{{x =(-sqrt(20))/2}}}
{{{x =(2sqrt(5))/2}}} OR {{{x =(-2sqrt(5))/2}}}
{{{x=sqrt(5)}}} OR {{{x=-sqrt(5)}}}
