(A) cannot both be positive 
(B) cannot both be negative 
(C) are always unequal 
(D) are always equal

3. If the zeroes of the quadratic polynomial ax2 + bx + c, c ≠ 0 are equal, then

(A) c and a have opposite signs 
(B) c and b have opposite signs 
(C) c and a have the same sign 
(D) c and b have  the same sign

(A) has no linear term and the constant term is negative.
(B) has no linear term and the constant term is positive.
