Solution for (2x^2-3)/(5-x) equation: 


D( x )

5-x = 0

5-x = 0

5-x = 0

5-x = 0 // - 5

-x = -5 // * -1

x = 5

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

(2*x^2-3)/(5-x) = 0

2*x^2 = 3 // : 2

x^2 = 3/2

x^2 = 3/2 // ^ 1/2

abs(x) = (3/2)^(1/2)

x = (3/2)^(1/2) or x = -(3/2)^(1/2)

x in { (3/2)^(1/2), -(3/2)^(1/2) }
