Subtract 1 1 from both sides of the equation. x2 = โ1 x 2 = - 1. Take the specified root of both sides of the equation to eliminate the exponent on the left side. x = ±โโ1 x = ± - 1. Rewrite โโ1 - 1 as i i. x = ±i x = ± i. The complete solution is the result of both the positive and negative portions of the solution. Tap for more steps...
