    Is My Approach to Proving lim (x^3+2x^2) = 1 Using ε/δ Definition Correct?

    Homework Statement Prove using ε/δ definition, lim x tends to -1 (x^3+2x^2) = 1 Homework Equations The Attempt at a Solution I have done to the step where δ(δ^2-δ-1) ≤ δ ≤ ε so i choose ε=min(2,ε) Not sure whether I am correct or not
