Question 444153
(x+2)m * (2x+3)m=91

x(2x+3)+2(2x+3)=91
2x^2+3x+4x+6=91
2x^2+7x-85=0

Find the roots of the equation by quadratic formula							
							
a=	2	b=	7	c=	-85		
							
b^2-4ac=49+680				
b^2-4ac=729
sqrt(729)=27
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}							
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}							
x1=(-7+27)/4		
x1=5						
x2=(-7-27)/4			
x2= -8.5
