Let me re-write the proposition:
p↔q⊕(¬p↔¬r)∧¬q.
Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:
p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1

Answer:
public static void quad(double a, double b, double c) {
double D = (Math.pow(b, 2)) - (4 * a * c);
if (D<0){
System.out.println("no real solutions");
}
}
Explanation:
The code snippet above implements the function in Java programming language
As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D
An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed
