No. No one can do what you ask.  I don't know what "set this equation up" really means in the first place, and in the second place, there is no equation.  An equation has an equals sign in it.  That's why they call them "equations."  Now, what you have is an expression.  To the extent that what you meant was to ask for help simplifying the expression involving radicals, proceed thus:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\sqrt{20}\ -\ 3\sqrt{45}\ +\ 4\sqrt{8}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\sqrt{4\,\cdot\,5}\ -\ 3\sqrt{9\,\cdot\,5}\ +\ 4\sqrt{4\,\cdot\,2}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\sqrt{4}\,\cdot\,\sqrt{5}\ -\ 3\sqrt{9}\,\cdot\,\sqrt{5}\ +\ 4\sqrt{4}\,\cdot\,\sqrt{2}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 4\sqrt{5}\ -\ 9\sqrt{5}\ +\ 8\sqrt{2}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ -5\sqrt{5}\ +\ 8\sqrt{2}]


And that's the best you can do with this one.
