Question 2:The formula of finding the roots of a quadratic expression is given here below
In finding the roots, the values a, b and c are identified and then the discriminant i.e.
b2  4ac is calculated If the discriminant is negative, then the roots are termed as "imaginary" otherwise the two roots are calculated using the formula. Write a pseudo code that will solve the problem above. The values of a, b and c are entered from the keyboard. (5mks) Answer
Explanations
Possible Marks Distribution( Award 1 mk for start & stop) ( Award 1 mk for reading a,b & c) ( Award 1 mk for testing discriminant) ( Award 1 mk for proper calculation of roots) ( Award 1 mk for output of roots & imaginary)
