Question

( M )
( a=0 )
Doots ar rom than
(0) ( 1 geqslant 0 )
( frac{-b}{6}>0 )
( Rightarrow(a-3)^{2}-4 a geqslant 0 quad 3 a=3 )
( Rightarrow a^{2}+9-10 a geq 0 )
3
( Rightarrow(a-9) )
( (a-1) geqslant 0 )
(D) SOR
' ( - )
3)
( f(0)>0 )
( 8 times 5 times 4 )
( frac{+}{0} frac{(1) cdot(12)}{4-2(n} )
( a> )
. ( a<10 )
( therefore a in[9,10 )
