A quadratic equation given roots is solved by using the relation

from the question,
sum of the root will be



and also, product of the roots will 
be 

now substituting the sum of roots and product of roots into the equation


as the quadratic equation for the root 3/4 and -4
 
        
             
        
        
        
Answer: Hi, the answer is 9/4 or C!
Step-by-step explanation:
You would take 2/7 and multiply both the top and bottom by 2 to make it 4/14, the. youd flip 4/14 into 14/4, then multiply the top numbers (9 and 14 by eachother to get 126) then multiply the bottom numbers ( 14 and 4 to get 56) and simplify the new fraction (126/56) to get 9/4!
 
        
             
        
        
        
Answer:
 x>-1
Step-by-step explanation:
first, you have to distribute. 12x+8-6>2x-16+8
then you have to combine like terms 12x+2>2x-8
you put the X's on one side 10x+2> -8
move the 2 to the -8 10x>-10
divide x>-1
 
        
                    
             
        
        
        
The solution of the equations is A) (-2,-4)
