**Consider the following statements :**

S_{1} : Let ax^{2 }+ bx + c = 0 be a quadratic equation, if b^{2} - 4ac > 0 then roots are real and distinct.

S_{2} : Let a,b,c,d ∈ I. Then the possible rational roots of the equation ax^{3} + bx^{2} + 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.

S_{3} : Let z = a + ib be a complex numbers where a,b ∈ C - R .Then z ≠ a - ib

S_{4} : If 2 (a + b√5)^{2} = 3 - √5/2 , then a, b ∈ Q.

State, in order, whether S_{1} , S_{2} , S_{3} , S_{4} are true or false
