Given,

6\sqrt{5}x^{2} -2x-4\sqrt{5}=0

We have to find the factors for this given expression,

Formula,

x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}

Here,

a=6\sqrt{5}, b= -2, c=4\sqrt{5}

Substitute the value in the above formula, we get

x=\frac{-2+-\sqrt{(-2)^{2}-4\times6\sqrt{5}\times4\sqrt{5}} }{2\times6\sqrt{5} }

x=\frac{-2+-\sqrt{4+96\times 5} }{12\sqrt{5} }

x=\frac{-2+-\sqrt{484} }{12\sqrt{5} }

x=\frac{4+22}{12\sqrt{5} } , x=\frac{4-22}{12\sqrt{5} }

x=\frac{13}{6\sqrt{5} }, \frac{-3}{2\sqrt{5} }

Therefore, the factors are x=\frac{13}{6\sqrt{5} }, \frac{-3}{2\sqrt{5} }.
