Arelation r on a set x is an equivalence relation if r is reflexive, symmetric, and transitive. fix an integer m ≥ 2 . show that the relation defined on the set z of integers by a r b ( a , b ∈ z ) if and only if a ≡ b ( mod m ) is an equivalence relation. (recall that a ≡ b ( mod m ) means that when dividing a by m and b by m you get the same remainder.)

What are the values of a, b, and c in the quadratic equation 0 = x2 – 3x - 2? a = 1, b = 3, c = 2 a=, b = -3,c=-2 a = 1, b = 3, c= 2 a = 1.0= -3, c = 2
