Solution for ((7p)/(7p-1))-((1)/(1-7p)) equation:


D( p )

1-(7*p) = 0

7*p-1 = 0

1-(7*p) = 0

1-(7*p) = 0

1-7*p = 0

1-7*p = 0 // - 1

-7*p = -1 // : -7

p = -1/(-7)

p = 1/7

7*p-1 = 0

7*p-1 = 0

7*p-1 = 0 // + 1

7*p = 1 // : 7

p = 1/7

p in (-oo:1/7) U (1/7:+oo)

(7*p)/(7*p-1)-(1/(1-(7*p))) = 0

(7*p)/(7*p-1)-(1-7*p)^-1 = 0

(7*p)/(7*p-1)-1/(1-7*p) = 0

(7*p*(1-7*p))/((7*p-1)*(1-7*p))+(-1*(7*p-1))/((7*p-1)*(1-7*p)) = 0

7*p*(1-7*p)-1*(7*p-1) = 0

1-49*p^2 = 0

(1-49*p^2)/((7*p-1)*(1-7*p)) = 0

(1-49*p^2)/((7*p-1)*(1-7*p)) = 0 // * (7*p-1)*(1-7*p)

1-49*p^2 = 0

-49*p^2 = -1 // : -49

p^2 = 1/49

p^2 = 1/49 // ^ 1/2

abs(p) = 1/7

p = 1/7 or p = -1/7

p in { 1/7}

p = -1/7
