x
x+2

...
(x+x+2)^2=x^2+(x+2)^2+126

(2x+2)^2=x^2+x^2+4x+4+126
4x^2+8x+4=2x^2+4x+130
2x^2+4x-126=0
a=2,b=4,c=-126		
							
b^2-4ac=16+1008				
b^2-4ac=1024
sqrt(	1024	)=	32
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}							
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}							
x1=(-4+	32)/4		
x1=7						
x2=(-4-32)/4			
x2= -9						
7 & 9
