Answer: The quotient is (2x+1)
Step-by-step explanation:
Here, the dividend =  
Divisor = 
By the long division method for finding the quotient we will follow the following steps,
Steps 1 :  Write dividend inside the division sign and divisor outside the division sign,
Step 2: Multiply the divisor by 2x and subtract the result by the dividend,
Step 3: Now, again multiply the divisor by 1,
Step 4: Subtract the result by the remaining dividend,
Since, further division is not possible,
Hence, the sum of all terms that are multiplied = 2x+1
Which is our quotient.
 
        
             
        
        
        
Since it’s a 10 team league and each team plays with the other team twice then 10+10=20, thus there would be 20 games played
