Question

[
begin{aligned}
f_{0}(1) &=9+6+c-9-6
&=c<0
end{aligned}
]
So ( f_{0}(1)<0 ) Mow graph wers be alurys below ( x ) axis as this has Img roots
So always ( f(x)<0 )
[
begin{array}{c}
6(21<0
49+26+c-9-6<0
end{array}
]
( 3 a+6+c<0 )

# 8. If the roots of the equation ax +bx+e-a-b=0 are non-real such that a, b,CER and cro then correct option is) is are: (A), atb so (B.) atc<2b (c.) 3a tbtc so Id.) A.Moj numbers a, b, c must be less then b.
