Solution for a+2/a+1-3a+2/2a+2 equation: 


D( a )

a = 0

a = 0

a = 0

a in (-oo:0) U (0:+oo)

a-(3*a)+(2/2)*a+2/a+1+2 = 0

a-3*a+(2/2)*a+2/a+1+2 = 0

2*a^-1-1*a^1+3*a^0 = 0

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

a^1*(3*a^1-1*a^2+2*a^0) = 0

a^1

3*a-a^2+2 = 0

3*a-a^2+2 = 0

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

DELTA = 17

DELTA > 0

a = (17^(1/2)-3)/(-1*2) or a = (-17^(1/2)-3)/(-1*2)

a = (17^(1/2)-3)/(-2) or a = (17^(1/2)+3)/2

a in { (17^(1/2)-3)/(-2), (17^(1/2)+3)/2} 

a in { (17^(1/2)-3)/(-2), (17^(1/2)+3)/2 }
