Answer:
The pairs of integer having two real solution for
 are




Step-by-step explanation:
Given

Now we will solve the equation by putting all the 6 pairs so we get the  following
 for 
 for 
 for 
 for 
 for 
 for 
The above  all are Quadratic equations inn general form 
where we have a,b and c constant values
So for a real Solution we must have

for 
 we have 
 which is less than 0 ∴ not a real solution.
for 
 we have 
 which is greater than 0 ∴ a real solution.
for 
 we have 
 which is greater than 0 ∴ a real solution.
for 
 we have 
 which is greater than 0 ∴ a real solution.
for 
 we have 
 which is equal to 0 ∴ a real solution.
for 
 we have 
 which is less than 0 ∴ not a real solution.
