Means the equation of the form 

In this the x^2 part is must because that only makes the equation a quadratic.
Looking at the four options given to you , only the option C has the missing x^2 term, which makes it a linear equation and hence the quadratic formula cannot be applied there .
So the right option for your question with the quadratic formula is 
option 
C
 
        
             
        
        
        
Answer: 1/2
Step-by-step explanation:
Number of red balloons = 17 
Number of purple balloons = 11 
Number of orange balloons = 3
