Factor 16 and see the - factor pairs and add them, see which add to -12
-1-16=-17 nope
-2-8=-10 nope
-4-4=-8
hmm
we will solve with math
xy=16
x+y=-12
minus  x both sides
y=-12-x
sub for y in other equation
x(-12-x)=16
-12x-x^2=16
add 12x+x^2 both sides
0=x^2+12x+16
use quadratic formula
if you have
ax^2+bx+c=0
x=

0=x^2+12x+16
a=1
b=12
c=16
x=

x=

x=

x=

x=

x=

 or 

aprox
x=-1.52786 or -10.4721
those are the numbers
the numbes are -1.52786 or -10.4721

You would get 9e+46 so not a real answer, just an estimate of what the answer is.
        
                    
             
        
        
        
2/3 or 66% , if its percentage we are talking about , so the answer is that you simply find 66% of 8 so multiply <span>0.666667</span>*8 and theres your answer round up to the nearest tenth and 5.333336 round it up and hopefully you have your answer
