D( x )
x+5 = 0
x+5 = 0
x+5 = 0
x+5 = 0 // - 5
x = -5
x in (-oo:-5) U (-5:+oo)
-8 = 3/(x+5) // - 3/(x+5)
-(3/(x+5))-8 = 0
-3*(x+5)^-1-8 = 0
-3/(x+5)-8 = 0
(-8*(x+5))/(x+5)-3/(x+5) = 0
-8*(x+5)-3 = 0
-8*x-43 = 0
(-8*x-43)/(x+5) = 0
(-8*x-43)/(x+5) = 0 // * x+5
-8*x-43 = 0
-8*x-43 = 0 // + 43
-8*x = 43 // : -8
x = 43/(-8)
x = -43/8
x = -43/8
