Fachtóirigh x^{2}-\frac{1}{6}x+\frac{1}{144}. Go ginearálta, nuair x^{2}+bx+c cearnóg fhoirfe é, is féidir é a fhachtóiriú i gcónaí mar \left(x+\frac{b}{2}\right)^{2}.
\sqrt{\left(x-\frac{1}{12}\right)^{2}}=\sqrt{\frac{145}{144}}
Tóg fréamh chearnach an dá thaobh den chothromóid.
x-\frac{1}{12}=\frac{\sqrt{145}}{12} x-\frac{1}{12}=-\frac{\sqrt{145}}{12}
Simpligh.
x=\frac{\sqrt{145}+1}{12} x=\frac{1-\sqrt{145}}{12}
Cuir \frac{1}{12} leis an dá thaobh den chothromóid.
