If a b c are distinct positive real numbers such that b(a+c)=2ac and given equation is ax^(2)+2bx+c=0 then the roots of the equation are ?

If a b c are distinct positive real numbers such that b(a+c)=2ac and given equation is ax^(2)+2bx+c=0 then (A) roots of given equation are imaginary (B) b is HM of a &c

Lat a,b and c be three distinct, positive,numbers such that 2b=a+c, then the equation ax^(2)+2bx+c=0 has

If b^(2)ge4ac for the equation ax^(4)+bx^(2)+c=0 then all the roots of the equation will be real if

if b^(2)ge4 ac for the equation ax^(4)+bx^(2) +c=0 then roots of the equation will be real if

If three distinct positive numbers a, b, c are in H.P.,then the equation ax^(2)+2bx+c=0 has:-

Let a,b and c be real numbers such that 4a+2b+c=0 and ab<0. Then the equation ax^(2)+bx+c=0

The quadratic equation ax^(2)+bx+c=0 has real roots if:

Let a,b and c be three real numbers,such that a+2b+4c0. Then the equation ax^(2)+bx+c=0

If a, b, c are positive real numbers such that the equations ax^(2) + bx + c = 0 and bx^(2) + cx + a = 0 , have a common root, then
