¿Cuál es una solución de la ecuación x2+1=0? - Brainly.lat
Web20 de jun. de 2023 · La ecuación x^2 + 1 = 0 no tiene soluciones reales. La razón es que el término x^2 siempre es mayor o igual a cero para cualquier valor real de x, y al sumarle 1, el resultado nunca puede ser igual a cero. Por lo tanto, en el conjunto de números reales, no hay ningún valor de x que satisfaga la ecuación.

Web30 de jul. de 2023 · Respuesta: Para determinar si la ecuación cuadrática x^2 + x + 1 = 0 tiene soluciones, podemos utilizar el discriminante. El discriminante se define como b^2 - 4ac, donde la ecuación cuadrática está en la forma ax^2 + bx + c = 0. En nuestro caso, a = 1, b = 1 y c = 1, entonces: Discriminante = b^2 - 4ac. Discriminante = 1^2 - 4 * 1 * 1.

Web30 de nov. de 2023 · 1. Add 1 to both sides of the equation: 2cos (x/2) = 1. 2. Divide both sides of the equation by 2: cos (x/2) = 1/2. 3. Take the inverse cosine (cos^-1) of both sides to get the value of x/2. Remember to consider the range of x: x/2 = π/3 or x/2 = 5π/3. 4. Multiply both sides of the equations by 2 to get the values of x: x = 2π/3 or x = 5π/3.
