Question

( begin{aligned} t^{2} &-frac{3 sqrt{5} t-5}{2}+frac{frac{3 sqrt{5}}{2} pm sqrt{frac{45}{4}+20}}{2} t=& frac{frac{3 sqrt{5}}{2} pm sqrt{frac{125}{4}}}{2} =& frac{frac{3 sqrt{5}}{2}+frac{5 sqrt{5}}{2}}{2} =& frac{3 sqrt{5}}{4} pm frac{5 sqrt{5}}{4} =& 2 sqrt{5} &-frac{sqrt{5}}{2} end{aligned} )
