Answer:
4 1/2
Step-by-step explanation:
Look at this expression as given in the original problem; the numbers, properly typewritten, are    -5  1/2,  - 4  1/4,  + 6  3/4.
We want to combine these three numbers into one.
To do this, we need the LCD; it is 4.
Thus, -5  1/2 is rewritten as  -5  2/4.
Then we have 
-5  2/4 - 4  1/4 + 6  3/4  = -5 -4 + 6 + 2/4 + 1/4 + 3/4.
This simplifies to:                 +3 + 6/4, or 3 + 1  + 2/4, or
                                                                       4  1/2
 
        
             
        
        
        
First set everything to 0.

Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
