Solution for 2a/a-5-a/a+5=26/a^2-25 equation: 


D( a )

a^2 = 0

a = 0

a^2 = 0

a^2 = 0

1*a^2 = 0 // : 1

a^2 = 0

a = 0

a = 0

a = 0

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

(2*a)/a-(a/a)-5+5 = 26/(a^2)-25 // - 26/(a^2)-25

(2*a)/a-(26/(a^2))-(a/a)-5+5+25 = 0

(2*a)/a-26*a^-2-5-1+5+25 = 0

-26*a^-2 = -26 // : -26

a^-2 = 1

-2 < 0

1/(a^2) = 1 // * a^2

1 = 1*a^2 // : 1

1 = a^2

a^2 = 1 // ^ 1/2

abs(a) = 1

a = 1 or a = -1

a in { 1, -1 }
