Solution for 3/4-1/b=-3b equation:


D( b )

b = 0

b = 0

b = 0

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

3/4-(1/b) = -3*b // + -3*b

3/4-(-3*b)-(1/b) = 0

3*b-b^-1+3/4 = 0

3*b^1-1*b^-1+3/4*b^0 = 0

(3*b^2+3/4*b^1-1*b^0)/(b^1) = 0 // * b^2

b^1*(3*b^2+3/4*b^1-1*b^0) = 0

b^1

3*b^2+(3/4)*b-1 = 0

3*b^2+(3/4)*b-1 = 0

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

DELTA = 201/16

DELTA > 0

b = ((201/16)^(1/2)-(3/4))/(2*3) or b = (-(3/4)-(201/16)^(1/2))/(2*3)

b = ((201/16)^(1/2)-3/4)/6 or b = (-((201/16)^(1/2)+3/4))/6

b in { (-((201/16)^(1/2)+3/4))/6, ((201/16)^(1/2)-3/4)/6}

b in { (-((201/16)^(1/2)+3/4))/6, ((201/16)^(1/2)-3/4)/6 }
