Question

( 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} )

# solve for v In?_6n + [n] +7=0.
