multiply both top and bottom of 2 3/4 to make it 12/16 then subtract from there.
 
        
                    
             
        
        
        
Anything multiplied by 0 =0
So what is left is 90x100x12x13x34 which is=47,736,000
        
             
        
        
        
Answer:
x²-8x-1=0
comparing above equation with ax²+bx+c=0
a=1
b=-8
c=-1
x=

=(--8+-√(64-4×1×-1)/2×1
=8+-√(64+4)/2
taking positive
x=(8+√68)/2=2(4+√17)/2=4+√17
taking negative 
x=(8-√68)/2=2(4-√17)/2=4-√17
