Question # Q.28 Let a & ß be the roots of the equation, a x2 + bx+c=0 where 10 & m>1
(B) a <0 & m<1
(C) a<0 & a

# Q.28 Let a & ß be the roots of the equation, a x2 + bx+c=0 where 10 & m>1
(B) a <0 & m<1
(C) a<0 & a

Solution ( lim _{x rightarrow m} frac{left|a x^{2}+b x+cright|}{a x^{2}+b x+c} quad Rightarrow A=1 )
( lim _{x rightarrow m} frac{|a(x-2)(x-beta)|}{a(x-2)(x-beta)}=1 )
numeraty should open with tre sign
( 50, quad a(m-alpha)(m-beta)>0 )
A) ( a>0 quad & quad m>1 quad ) tre
BS ( a<0 )
( 8 mathrm{m}<1 )
-ve ( x )
ef ( a<0 quad & quad alpha

Solution
