Solution for (2b/b^2-14b+49)-(14/b^2-14b+49) equation:


D( b )

b^2 = 0

b^2 = 0

b^2 = 0

1*b^2 = 0 // : 1

b^2 = 0

b = 0

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

14*b-(14*b)+(2*b)/(b^2)-(14/(b^2))-49+49 = 0

14*b-14*b+(2*b)/(b^2)-14*b^-2-49+49 = 0

2*b^-1-14*b^-2 = 0

t_1 = b^-1

2*t_1^1-14*t_1^2 = 0

2*t_1-14*t_1^2 = 0

DELTA = 2^2-(-14*0*4)

DELTA = 4

DELTA > 0

t_1 = (4^(1/2)-2)/(-14*2) or t_1 = (-4^(1/2)-2)/(-14*2)

t_1 = 0 or t_1 = 1/7

t_1 = 0

b^-1+0 = 0

b^-1 = 0

1*b^-1 = 0 // : 1

b^-1 = 0

b naleu017Cy do O

t_1 = 1/7

b^-1-1/7 = 0

1*b^-1 = 1/7 // : 1

b^-1 = 1/7

-1 < 0

1/(b^1) = 1/7 // * b^1

1 = 1/7*b^1 // : 1/7

7 = b^1

b = 7

b = 7
