Question 733212
{{{3x^2-5x-8=0}}}

compare with equation {{{ax^2+bx+c=0}}}


a=	3	,	b=	-5	,	c=	-8
							
b^2-4ac=	25	+	96				
b^2-4ac=	121						
{{{	sqrt(	121	)=	11	}}}		
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}							
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}							
x1=(	5	+	11	)/	6		
x1=	2.67						
{{{x2=(-b-sqrt(b^2-4ac))/(2a)}}}							
x2=(	5	-11	) /	6			
x2=	-1.00						
							
2.67	, -1
