Solution for (x^2+3x-44)/(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)

(x^2+3*x-44)/(x+7) = 0

x^2+3*x-44 = 0

x^2+3*x-44 = 0

DELTA = 3^2-(-44*1*4)

DELTA = 185

DELTA > 0

x = (185^(1/2)-3)/(1*2) or x = (-185^(1/2)-3)/(1*2)

x = (185^(1/2)-3)/2 or x = (-(185^(1/2)+3))/2

(x+(185^(1/2)+3)/2)*(x-((185^(1/2)-3)/2)) = 0

((x+(185^(1/2)+3)/2)*(x-((185^(1/2)-3)/2)))/(x+7) = 0

( x+(185^(1/2)+3)/2 )

x+(185^(1/2)+3)/2 = 0 // - (185^(1/2)+3)/2

x = -((185^(1/2)+3)/2)

( x-((185^(1/2)-3)/2) )

x-((185^(1/2)-3)/2) = 0 // + (185^(1/2)-3)/2

x = (185^(1/2)-3)/2

x in { -((185^(1/2)+3)/2), (185^(1/2)-3)/2 }
