Question 452963
Find the roots of the equation by quadratic formula					
					
a=	14	,b=	-45	,c=	-14
					
b^2-4ac=	2025	+	784		
b^2-4ac=	2809	
{{{sqrt(2809)}}}=53
			
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}					
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}					
{{{x1=(45+sqrt(2809))/(28)}}}					
x1=(45+	53)/28
x1=3.5				
x2=(45-53)/28	
x2= -0.29
