Solve for x x^2+1=0 | Mathway
WEBSubtract 1 1 from both sides of the equation. x2 = −1 x 2 = - 1. Take the specified root of both sides of the equation to eliminate the exponent on the left side. x = ±√−1 x = ± - 1. Rewrite √−1 - 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...

Solve x^2+x+1=0 | Microsoft Math Solver
WEBQuadratic Equation. x2+x+1 = 0. Similar Problems from Web Search. Moving from x2 + x + 1 = 0 to x + 1 + x1 = 0 seems to introduce a solution, how is this possible? https://math.stackexchange.com/q/2692085. In effect, you have taken the equation x2 +x+1 = 0, divided by x to get x+1+ x1 = 0 and then multiplied by x−1 to get x2 − x1 = 0.

Solving quadratic equations by factoring (article) | Khan Academy
WEBWhy is this a quadratic equation? x 2 + 2 x − 3 = 0. This is a product of two expressions that is equal to zero. Note that any x value that makes either ( x − 1) or ( x + 3) zero, will make their product zero. ( x − 1) ( x + 3) = 0 ↙ ↘ x − 1 = 0 x + 3 = 0 x = 1 x = − 3.
