( rightarrow 70 ) solve ( operatorname{lom} x ) ( r^{2}-6 x+[x]+7=0 ) is ( x^{2}-6 x+x+7=0 ) ( i i x^{2}-6 x-k+7=0 ) ( x^{2}-5 x+7=0 ) ( x^{2}-7 x+7=0 ) ( D=25-35 mathrm{r}-10 ) ( D=49-2 e=21 ) ( therefore quad x=frac{6 pm sqrt{-10}}{2} ) ( frac{sqrt{x}}{2}=frac{6 pm sqrt{21}}{2} ) ( x=frac{6 pm 10 i}{2} )
