Solution for (2x^2+16x+20)/(x+6) equation: 


D( x )

x+6 = 0

x+6 = 0

x+6 = 0

x+6 = 0 // - 6

x = -6

x in (-oo:-6) U (-6:+oo)

(2*x^2+16*x+20)/(x+6) = 0

2*x^2+16*x+20 = 0

2*(x^2+8*x+10) = 0

x^2+8*x+10 = 0

DELTA = 8^2-(1*4*10)

DELTA = 24

DELTA > 0

x = (24^(1/2)-8)/(1*2) or x = (-24^(1/2)-8)/(1*2)

x = (2*6^(1/2)-8)/2 or x = (-2*6^(1/2)-8)/2

2*(x-((-2*6^(1/2)-8)/2))*(x-((2*6^(1/2)-8)/2)) = 0

(2*(x-((-2*6^(1/2)-8)/2))*(x-((2*6^(1/2)-8)/2)))/(x+6) = 0

( x-((-2*6^(1/2)-8)/2) )

x-((-2*6^(1/2)-8)/2) = 0 // + (-2*6^(1/2)-8)/2

x = (-2*6^(1/2)-8)/2

( x-((2*6^(1/2)-8)/2) )

x-((2*6^(1/2)-8)/2) = 0 // + (2*6^(1/2)-8)/2

x = (2*6^(1/2)-8)/2

x in { (-2*6^(1/2)-8)/2, (2*6^(1/2)-8)/2 }
