(a) A quadratic equation in mathematics is of the form ax2 + bx + c =0. The discriminant of such an equation is given by
D2 = (b2 – 4ac) or = √(
2 − 4 . The roots of a quadratic equation are
given by 1,2 =
−±√(
2−4
2
, i. e., 1 =−+√(
2−4
2
and
2 =
−−√(
2−4
2
.
(i) if D > 0, then the quadratic equation has real roots 1 2
(ii) if D = 0, then the quadratic equation has one root, i. e., the roots are
the same 1 = 2

(iii) If D < 0, then the quadratic equation has complex roots given by
1,2 =
−±√(4−
2
2
.
Draw a flow chart for finding the roots of a quadratic equation as indicated
in a (i), (ii) and (iii). (10 marks).
(b) Write part of a program code (NOT a complete program) using an if--
-else statement for checking the roots given in (a) (i), (ii) and (iii).(10
marks).
