2.2.6 Consider the following proposition, where x is assumed to be a real number. x3 – 3x2 – 2x+6=0 → x = 3 (*) - (a) Is the proposition (*) true or false? Justify your answer. Is its converse true? (b) Repeat part (a) for the proposition x3 – 3x? – 2x +6=0 = x # 3 (c) Does anything change about the truth status of (*) if we assume that it is a statement about rational numbers x? Explain.
