Solution for 13z^1/7(6z^6/7-2z^14) equation:


z in (-oo:+oo)

((13*z^1)/7)*((6*z^6)/7-(2*z^14)) = 0

((13*z)/7)*((6*z^6)/7-2*z^14) = 0

13/7*z*(6/7*z^6-2*z^14) = 0

6/7*z^6-2*z^14 = 0

2*z^6*(3/7-z^8) = 0

-1*z^8 = -3/7 // : -1

z^8 = 3/7

z^8 = 3/7 // ^ 1/8

abs(z) = (3/7)^(1/8)

z = (3/7)^(1/8) or z = -(3/7)^(1/8)

2*z^6*(z-(3/7)^(1/8))*(z+(3/7)^(1/8)) = 0

13/7*2*z*z^6*(z-(3/7)^(1/8))*(z+(3/7)^(1/8)) = 0

( 13/7*z )

13/7*z = 0 // : 13/7

z = 0

( 2*z^6 )

2*z^6 = 0 // : 2

z^6 = 0

z = 0

( z+(3/7)^(1/8) )

z+(3/7)^(1/8) = 0 // - (3/7)^(1/8)

z = -(3/7)^(1/8)

( z-(3/7)^(1/8) )

z-(3/7)^(1/8) = 0 // + (3/7)^(1/8)

z = (3/7)^(1/8)

z in { 0, 0, -(3/7)^(1/8), (3/7)^(1/8) }
