Solution for (7m^2-60+27)/(m+9) equation: 


D( m )

m+9 = 0

m+9 = 0

m+9 = 0

m+9 = 0 // - 9

m = -9

m in (-oo:-9) U (-9:+oo)

(7*m^2-60+27)/(m+9) = 0

(7*m^2-33)/(m+9) = 0

7*m^2 = 33 // : 7

m^2 = 33/7

m^2 = 33/7 // ^ 1/2

abs(m) = (33/7)^(1/2)

m = (33/7)^(1/2) or m = -(33/7)^(1/2)

m in { (33/7)^(1/2), -(33/7)^(1/2) }
