Solution for (2b^3+10b^2-b+5)/(b+5) equation:


D( b )

b+5 = 0

b+5 = 0

b+5 = 0

b+5 = 0 // - 5

b = -5

b in (-oo:-5) U (-5:+oo)

t_2 = 0

(2*b^3+10*b^2-b+5)/(b+5)+t_2 = 0

(2*b^3+10*b^2-b+5)/(b+5)+(t_2*(b+5))/(b+5) = 0

t_2*(b+5)+2*b^3+10*b^2-b+5 = 0

2*b^3+10*b^2-b+b*t_2+5*t_2+5 = 0

2*b^3+10*b^2-b+b*t_2+5*t_2+5 = 0

2*b^3+10*b^2-b+b*t_2+5*t_2+5

b*(2*b^2-1)+10*b^2+b*t_2+5*t_2+5

b*(10*b+t_2)+b*(2*b^2-1)+5*t_2+5

5*(t_2+1)+b*(10*b+t_2)+b*(2*b^2-1)

b*(2*b^2+10*b+t_2-1)+5*(t_2+1)

6*(2*b^2+10*b+t_2-1)

(6*(2*b^2+10*b+t_2-1))/(b+5) = 0

(6*(2*b^2+10*b+t_2-1))/(b+5) = 0 // * b+5

6*(2*b^2+10*b+t_2-1) = 0

2*b^2+10*b+t_2-1 = 0

DELTA = 10^2-(2*4*(t_2-1))

DELTA = 100-8*(t_2-1)

100-8*(t_2-1) = 0

100-8*(t_2-1) = 0

108-8*t_2 = 0

108-8*t_2 = 0

108-8*t_2 = 0 // - 108

-8*t_2 = -108 // : -8

t_2 = -108/(-8)

t_2 = 27/2

DELTA = 0 <=> t_4 = 27/2

b = -10/(2*2) i t_2 = 27/2

b = -5/2 i t_2 = 27/2

( b = ((100-8*(t_2-1))^(1/2)-10)/(2*2) or b = (-(100-8*(t_2-1))^(1/2)-10)/(2*2) ) i t_2 > 27/2

( b = ((100-8*(t_2-1))^(1/2)-10)/4 or b = (-((100-8*(t_2-1))^(1/2)+10))/4 ) i t_2 > 27/2

t_2-27/2 > 0

t_2-27/2 > 0 // + 27/2

t_2 > 27/2

b in { -5/2, ((100-8*(0-1))^(1/2)-10)/4, (-((100-8*(0-1))^(1/2)+10))/4 }
