Given the quadratic equation:

[tex]x^2+5x-5=0[/tex]

Using the general solution for quadratic equations:

[tex]ax^2+bx+c=0\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

From the problem, we identify:

[tex]\begin{gathered} a=1 \\ b=5 \\ c=-5 \end{gathered}[/tex]

Then:

[tex]x=\frac{-5\pm\sqrt{25+20}}{2}=\frac{-5\pm3\sqrt{5}}{2}[/tex]

And the solution set is:

[tex]\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}][/tex]
