Question 977120
{{{4(6x-1)^2 -5 =223}}}
=> {{{4(36x^2 + 1 -12x) -5 =223}}}
=> {{{144x^2 -48x + 4 -5 -223 = 0}}}
=> {{{144x^2 -48x - 224 =0}}}
=> {{{9x^2 - 3x - 14 =0}}}
=> {{{x= (3+sqrt(3^2-4*9*(-14)))/(2*9)}}} or {{{x= (3-sqrt(3^2-4*9*(-14)))/(2*9)}}}
=> {{{x=(1+sqrt(57))/6}}} and {{{x=(1-sqrt(57))/6}}}
