Solution for (m^2-7m-11)/(m-8) equation: 


D( m )

m-8 = 0

m-8 = 0

m-8 = 0

m-8 = 0 // + 8

m = 8

m in (-oo:8) U (8:+oo)

(m^2-(7*m)-11)/(m-8) = 0

(m^2-7*m-11)/(m-8) = 0

m^2-7*m-11 = 0

m^2-7*m-11 = 0

DELTA = (-7)^2-(-11*1*4)

DELTA = 93

DELTA > 0

m = (93^(1/2)+7)/(1*2) or m = (7-93^(1/2))/(1*2)

m = (93^(1/2)+7)/2 or m = (7-93^(1/2))/2

(m-((7-93^(1/2))/2))*(m-((93^(1/2)+7)/2)) = 0

((m-((7-93^(1/2))/2))*(m-((93^(1/2)+7)/2)))/(m-8) = 0

( m-((7-93^(1/2))/2) )

m-((7-93^(1/2))/2) = 0 // + (7-93^(1/2))/2

m = (7-93^(1/2))/2

( m-((93^(1/2)+7)/2) )

m-((93^(1/2)+7)/2) = 0 // + (93^(1/2)+7)/2

m = (93^(1/2)+7)/2

m in { (7-93^(1/2))/2, (93^(1/2)+7)/2 }
