    [tex]11x^2 – 4x = 1[/tex]
    [tex]11x^{2} – 4x – 1 = 1 – 1[/tex]
    [tex]11x^{2} – 4x – 1 = 0[/tex]
    [tex]x = frac{-(-4) u00b1 sqrt{(-4)^{2} – 4(11)(-1)}}{2(11)}[/tex]
    [tex]x = frac{4 u00b1 sqrt{16 + 44}}{22}[/tex]
    [tex]x = frac{4 u00b1 sqrt{60}}{22}[/tex]
    [tex]x = frac{4 u00b1 2sqrt{15}}{22}[/tex]
    [tex]x = frac{2 u00b1 sqrt{15}}{11}[/tex]
    [tex]x = frac{2 + sqrt{15}}{11} bold{or} x = frac{2 – sqrt{15}}{11}[/tex]
