El Teorema del Binomio

¿Te has preguntado por qué x+yx+y² siempre da x² + 2xy + y²? El teorema del binomio te explica este patrón y te da la fórmula para cualquier potencia.

La fórmula general es: x+yx+yⁿ = Σ(n choose r) xⁿ⁻ʳ yʳ, donde los coeficientes binomiales (n choose r) determinan los números que van delante de cada término. Estos coeficientes también se pueden calcular como n!/r!(nr)!r!(n-r)!.

Por ejemplo, para expandir 2a+b2a+b⁶, identificas que x=2a, y=b, y n=6. Luego aplicas la fórmula término por término, calculando cada coeficiente binomial.

Tip clave: Los exponentes de x van disminuyendo mientras que los de y van aumentando, pero siempre suman n.

Término General del Desarrollo

No siempre necesitas expandir todo el binomio - a veces solo te piden un término específico. El término general que contiene xʳ en x+yx+yⁿ es: nchoosenrn choose n-r xʳ yⁿ⁻ʳ.

Para encontrar un término específico, primero identifica qué valor de r necesitas. Por ejemplo, si buscas x¹⁵ en x+y2/2√x + y²/2³², piensa: ¿cuántas veces debo elevar √x para obtener x¹⁵?

Como (√x)³⁰ = x¹⁵, entonces r=30. Con n=32 y r=30, el término es: (32 choose 2)(√x)³⁰y2/2y²/2² = 496 x¹⁵ y⁴/4 = 124 x¹⁵ y⁴.

Estrategia ganadora: Siempre identifica primero el exponente que necesitas, luego trabaja hacia atrás para encontrar r.

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.
