Answer:


x=3+\frac{\sqrt{4L^(2)+1}}{L} and
x=3-\frac{\sqrt{4L^(2)+1}}{L}

Explanation:

we have


L=\frac{1} {√(x^2-6x + 5)}

Solve for x

That means-----> isolate the variable x

squared both sides


L^(2) =(\frac{1} {√(x^2-6x + 5)})^(2)\\ \\L^(2)=\frac{1} {{x^2-6x + 5}}\\ \\x^2-6x + 5=(1)/(L^(2))\\ \\x^2-6x=(1)/(L^(2))-5\\ \\x^2-6x+9=(1)/(L^(2))-5 +9\\ \\x^2-6x+9=(1)/(L^(2))+4\\ \\(x-3)^2=(4L^(2)+1)/(L^(2))

Take the square root both sides


(x-3)=(+/-)\sqrt{(4L^(2)+1)/(L^(2))}\\ \\x=3(+/-)\frac{\sqrt{4L^(2)+1}}{L}

therefore


x=3+\frac{\sqrt{4L^(2)+1}}{L}


x=3-\frac{\sqrt{4L^(2)+1}}{L}
