The equation 𝑥²=1 has two solutions. They are 𝑥 = 1 and 𝑥 = -1. We can see that if you substitute 1 in as 𝑥, 1² = 1. If instead you substitute -1 as 𝑥, (-1)² = (-1)*(-1) = 1. In general, 𝑥² = a, where a is a positive real number, has solutions 𝑥 = √a and 𝑥 = -√a. If a is not a positive number, or is not a real number, but rather a complex number, then we need to expand our horizons. There will still be two answers, as with the positive number case. ✅ Follow @math
