If `a, b and c` are in arithmetic progression, then the roots of the equation `ax^2-2bx + c = 0` are

If a, b, c are in arithmetic progression, then the roots of the equation ax^2-2bx+c=0 are

If a, b and c are in geometric progression and the roots of the equation ax^(2) + 2bx + c = 0 are alpha and beta and those of cx^(2) + 2bx + a = 0 are gamma and delta

If a,b and c are in geometric progression and the roots of the equations ax^(2)+2bx+c=0 are alpha and beta and those of cx^(2)+2bx+a=0 are gamma and delta then

If a,b,c are in A.P. then the roots of the equation ax^(2)+2bx+c=0 are

If the roots of the equation ax^(2)+bx+c=0 are equal then c=?

If the roots of the equation ax^2+bx+c=0(a!=0) be equal then
