Solution

Claro, aquí tienes la solución paso a paso:

  1. Comienza con la ecuación cuadrática dada: x2+6x10=0 x^2 + 6x - 10 = 0

  2. Mueve el término constante al otro lado de la ecuación: x2+6x=10 x^2 + 6x = 10

  3. Para completar el cuadrado, toma el coeficiente del término lineal (6), divídelo por 2 y luego elévalo al cuadrado: (62)2=32=9 \left(\frac{6}{2}\right)^2 = 3^2 = 9

  4. Añade y resta este valor (9) en el lado izquierdo de la ecuación: x2+6x+99=10 x^2 + 6x + 9 - 9 = 10

  5. Reescribe la ecuación agrupando los términos que forman un trinomio cuadrado perfecto: (x+3)29=10 (x + 3)^2 - 9 = 10

  6. Mueve el -9 al otro lado de la ecuación: (x+3)2=10+9 (x + 3)^2 = 10 + 9 (x+3)2=19 (x + 3)^2 = 19

  7. Toma la raíz cuadrada de ambos lados de la ecuación: x+3=±19 x + 3 = \pm \sqrt{19}

  8. Finalmente, despeja x x : x=3±19 x = -3 \pm \sqrt{19}

Por lo tanto, las soluciones de la ecuación cuadrática son: x=3+19 x = -3 + \sqrt{19} y x=319 x = -3 - \sqrt{19} .
