6

Si amplías (x−y)^2, ¿qué término no aparece?

7

¿Qué forma correcta es (m+n)^2?

8

¿Qué se obtiene si restas las potencias en (a−b)(a+b)?

9

¿Qué representa 2ab en la expansión de (a+b)^2?

10

¿Qué no es un producto notable clásico?

Explicación

El cuadrado de una resta es a^2 − 2ab + b^2.

Producto de suma por resta da diferencia de cuadrados.

Es la diferencia de cuadrados.

Corresponde al cuadrado de la suma.

En (x−y)^2 aparecen x^2, y^2 y −2xy.

Es la expansión de la suma al cuadrado.

Es igual a la diferencia de cuadrados.

2ab es el doble producto de a y b.

Los notables clásicos son (a+b)^2, (a−b)^2 y (a+b)(a−b); a^3+b^3 no es uno de ellos.
