Question 775550
x^2=-x+7

x^2+x-7=0

Find the roots of the equation by quadratic formula								
			iiiii					
a=	1	,	b=	1	,	c=	-7	
								
b^2-4ac=	1	+	28					
b^2-4ac=	29							
{{{	sqrt(	29	)=	5.39	}}}			
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}								
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}								
x1=(	-1	+	5.39	)/	2			
x1=	2.19							
{{{x2=(-b-sqrt(b^2-4ac))/(2a)}}}								
x2=(	-1	-5.39	) /	2				
x2=	-3.19							

((2.19,-3.19)
