Consider the following statements :

S1 : Let ax2 + bx + c = 0 be a quadratic equation, if b2 - 4ac > 0 then roots are real and distinct.

S2 : Let a,b,c,d ∈ I. Then the possible rational roots of the equation ax3 + bx2 + cx + d = 0 are of the form p/q where p is an integral divisor of d and q is an integral divisor of a.

S3 : Let z = a + ib be a complex numbers where a,b ∈ C - R .Then z ≠ a - ib

S4 : If 2 (a + b√5)2 = 3 - √5/2 , then a, b ∈ Q.

State, in order, whether S1 , S2 , S3 , S4 are true or false
