Multiple choice If x + \frac{1}{x} =2, then x2 + \frac{1}{x^2} is 0 4 2 6 Reveal answer Fill a bubble to check yourself C Correct answer Explanation Given x + 1/x = 2, square both sides: (x + 1/x)^2 = 2^2, which is x^2 + 2(x)(1/x) + 1/x^2 = 4. This simplifies to x^2 + 2 + 1/x^2 = 4, so x^2 + 1/x^2 = 2.
