if da diff of da roots of da eq ax² -bx +c =0 is equal to the diff of ad roots of da eq x² -cx+b=0 and b is not equal to c then b+c =

a)0      b)2       c)4             d)-4

if da roots of da eq  (b-c) x² +(c-a)x +c(a-b) =0 are equal then a,b,c are in

a)AP         b)GP          c)HP      D)A.G.P

i say just go fr eamcet coz ull get OU wth dat rank n also a gud branch

if f(x)= ax² +bx+c g(x) = -ax²+bx+c  where ac is not equal to 0 then f(x) .g(x) =0has

A)at least 3 real roots

b)no real roots

c)at least 2 real roots

D 2 real roots n 2 imaginary roots

plzzz help

if da eq x³ -3x +a=0 has distinct roots between 0 and 1 then da value of a is?

 a)2   b)1/2   c)3   d)none of dese

naaa da ans is acb r in GP plzzz help
