Solution for (7-3m)/(m^2-25) equation: 


D( m )

m^2-25 = 0

m^2-25 = 0

m^2-25 = 0

1*m^2 = 25 // : 1

m^2 = 25

m^2 = 25 // ^ 1/2

abs(m) = 5

m = 5 or m = -5

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

(7-(3*m))/(m^2-25) = 0

(7-3*m)/(m^2-25) = 0

7-3*m = 0 // - 7

-3*m = -7 // : -3

m = -7/(-3)

m = 7/3

m = 7/3
