Solution for 8/(b+4)(b-4)-7/(b-4)(b+3) equation: 


D( b )

b+4 = 0

b-4 = 0

b+4 = 0

b+4 = 0

b+4 = 0 // - 4

b = -4

b-4 = 0

b-4 = 0

b-4 = 0 // + 4

b = 4

b in (-oo:-4) U (-4:4) U (4:+oo)

(8/(b+4))*(b-4)-((7/(b-4))*(b+3)) = 0

(8/(b+4))*(b-4)-7*(b+3)*(b-4)^-1 = 0

(8*(b-4))/(b+4)+(-7*(b+3))/(b-4) = 0

(8*(b-4)^2)/((b+4)*(b-4))+(-7*(b+3)*(b+4))/((b+4)*(b-4)) = 0

8*(b-4)^2-7*(b+3)*(b+4) = 0

b^2-113*b+44 = 0

b^2-113*b+44 = 0

b^2-113*b+44 = 0

DELTA = (-113)^2-(1*4*44)

DELTA = 12593

DELTA > 0

b = (12593^(1/2)+113)/(1*2) or b = (113-12593^(1/2))/(1*2)

b = (7*257^(1/2)+113)/2 or b = (113-7*257^(1/2))/2

(b-((113-7*257^(1/2))/2))*(b-((7*257^(1/2)+113)/2)) = 0

((b-((113-7*257^(1/2))/2))*(b-((7*257^(1/2)+113)/2)))/((b+4)*(b-4)) = 0

((b-((113-7*257^(1/2))/2))*(b-((7*257^(1/2)+113)/2)))/((b+4)*(b-4)) = 0 // * (b+4)*(b-4)

(b-((113-7*257^(1/2))/2))*(b-((7*257^(1/2)+113)/2)) = 0

( b-((113-7*257^(1/2))/2) )

b-((113-7*257^(1/2))/2) = 0 // + (113-7*257^(1/2))/2

b = (113-7*257^(1/2))/2

( b-((7*257^(1/2)+113)/2) )

b-((7*257^(1/2)+113)/2) = 0 // + (7*257^(1/2)+113)/2

b = (7*257^(1/2)+113)/2

b in { (113-7*257^(1/2))/2, (7*257^(1/2)+113)/2 }
