Answer:
The leading coefficient is 1 and the linear term coefficient is an even number
Step-by-step explanation:
Leading coefficient must be one for the application of completing square method. If the completing square is not one than we must apply other methods like Ac method, quadratic formula to solve the equation. To solve the equation with completing square the numerical value must be on other side of the equation. In this method we multiply linear term’s coefficient with one-half and square it therefore, completing square is suitable method for the equation having leading coefficient is 1 and linear coefficient is even.
 
        
             
        
        
        
Answer:
First =  Poppy seed  = 3x10^-4 grams  = 0.0003 grams 
Second  =  sesame seeds  =  3.64x10^-6 grams  = 0.00364 grams
third  = 250 pumpkin seeds 21 grams  = one seed 0.084 grams
Step-by-step explanation:
3.64x10^-6 kilograms *1000gr/Kilograms =  0.00364 grams
21/250 = 0.0084 grams one seeds
