Subject: why doesn't work

why method pierw doesn't run?


class Wielomian
   attr_accessor :a, :b, :c

 def initialize
   @d
 end

 def +(other)
   result = Wielomian.new
   result.a = self.a + other.a
   result.b = self.b + other.b
   result.c = self.c + other.c
   result
 end

 def -(other)
   result = Wielomian.new
   result.a = self.a - other.a
   result.b = self.b - other.b
   result.c = self.c - other.c
   result
 end

def *(other)
   result = Wielomian.new
   result.a = self.a * other.a
   result.b = self.b * other.b
   result.c = self.c * other.c
   result
 end

def /(other)
   result = Wielomian.new
   result.a = self.a / other.a
   result.b = self.b / other.b
   result.c = self.c / other.c
   result
 end

 def delta
   @d = b**2 - (4*a*c)
 end

def pierw
  x1 = -(b - (Math.sqrt(@d))/2*a)
 end

end
