If he equation x^(3)+ax^(2)+bx+216=0 has three real roots in G.P.then b/a has the value equal to

If ax^(2) +bx +c=0 has equal roots. Then c is equal to :

If the roots of the equation x^(3) + bx^(2) + cx - 1 = 0 form an increasing G.P., then b belongs to the interval

If the roots of the equation x^(3) + bx^(2) + cx - 1 = 0 form an increasing G.P., then b belongs to the interval

If the equations ax^2 + bx + c = 0 and x^2 + x + 1= 0 has one common root then a : b : c is equal to
