Solution for (2x^2-11x-15)/(x+7) equation: 


D( x )

x+7 = 0

x+7 = 0

x+7 = 0

x+7 = 0 // - 7

x = -7

x in (-oo:-7) U (-7:+oo)

(2*x^2-(11*x)-15)/(x+7) = 0

(2*x^2-11*x-15)/(x+7) = 0

2*x^2-11*x-15 = 0

2*x^2-11*x-15 = 0

DELTA = (-11)^2-(-15*2*4)

DELTA = 241

DELTA > 0

x = (241^(1/2)+11)/(2*2) or x = (11-241^(1/2))/(2*2)

x = (241^(1/2)+11)/4 or x = (11-241^(1/2))/4

(x-((11-241^(1/2))/4))*(x-((241^(1/2)+11)/4)) = 0

((x-((11-241^(1/2))/4))*(x-((241^(1/2)+11)/4)))/(x+7) = 0

( x-((11-241^(1/2))/4) )

x-((11-241^(1/2))/4) = 0 // + (11-241^(1/2))/4

x = (11-241^(1/2))/4

( x-((241^(1/2)+11)/4) )

x-((241^(1/2)+11)/4) = 0 // + (241^(1/2)+11)/4

x = (241^(1/2)+11)/4

x in { (11-241^(1/2))/4, (241^(1/2)+11)/4 }
