Simplificación de fracciones con polinomios

¿Sabías que simplificar fracciones con polinomios es como hacer una limpieza ordenada? Solo necesitas factorizar y cancelar los términos comunes.

Para simplificar x36x2+11x6x22x\frac{x^3-6x^2+11x-6}{x^2-2x}, primero factorizas el numerador. Usando la regla de Ruffini o probando valores, encuentras que las raíces son x=1, x=2 y x=3. Esto significa que x36x2+11x6=(x1)(x2)(x3)x^3-6x^2+11x-6=(x-1)(x-2)(x-3).

El denominador es más fácil: x22x=x(x2)x^2-2x = x(x-2). Solo sacas factor común.

¡Ojo! Siempre verifica tus factorizaciones sustituyendo las raíces en el polinomio original.

Ahora sustituyes y obtienes (x1)(x2)(x3)x(x2)\frac{(x-1)(x-2)(x-3)}{x(x-2)}. Cancelas el factor común (x2)(x-2) y te queda (x1)(x3)x\frac{(x-1)(x-3)}{x}. ¡Listo!

Suma y resta de fracciones con polinomios

Sumar fracciones con polinomios es igual que con números normales: necesitas un denominador común. La diferencia es que trabajas con expresiones algebraicas.

Para resolver x21x243x2+2x1x+1\frac{x^2-1}{x^2-4} - \frac{3}{x-2} + \frac{2x-1}{x+1}, primero factorizas los denominadores. El x24x^2-4 se convierte en (x+2)(x2)(x+2)(x-2), mientras que los otros ya están factorizados.

El mínimo común múltiplo será (x+1)(x+2)(x2)(x+1)(x+2)(x-2). Ahora multiplicas cada numerador por los factores que le faltan a su denominador para llegar al mcm.

Consejo pro: Usa paréntesis cuando restes fracciones para evitar errores de signos.

Una vez que tienes el mismo denominador, sumas o restas los numeradores: (x2+x+1)(3x2+9x+6)+(2x3x28x+4)(x^2+x+1) - (3x^2+9x+6) + (2x^3-x^2-8x+4). Operas término a término y obtienes 3x33x216x1(x+1)(x+2)(x2)\frac{3x^3-3x^2-16x-1}{(x+1)(x+2)(x-2)}.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha KlichAndroid user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
