¿Cuál es la fórmula para la diferencia de dos cuadrados?
(a^2 - b^2 = (a + b)(a - b))
(a^2 + b^2 = (a + b)^2)
(a^2 - b^2 = (a - b)^2)
(a^2 + b^2 = (a - b)^2)

¿Cómo se expresa el trinomio cuadrado perfecto?
(a^2 + 2ab + b^2 = (a + b)^2)
(a^2 - 2ab + b^2 = (a - b)^2)
(a^2 + b^2 = (a + b)^2)
(a^2 - b^2 = (a - b)^2)

¿Cuál es la fórmula para la suma de dos cubos?
(a^3 + b^3 = (a + b)(a^2 - ab + b^2))
(a^3 - b^3 = (a - b)(a^2 + ab + b^2))
(a^3 + b^3 = (a - b)(a^2 + ab + b^2))
(a^3 - b^3 = (a + b)(a^2 - ab + b^2))

¿Cómo se expresa el cuadrado de un polinomio (x - 3y + 2z)^2?
(x^2 + 9y^2 + 4z^2 + 2x(-3y) + 2x(2z) + 2(-3y)(2z))
(x^2 + 9y^2 + 4z^2 - 2x(-3y) - 2x(2z) - 2(-3y)(2z))
(x^2 - 9y^2 + 4z^2 + 2x(-3y) + 2x(2z) + 2(-3y)(2z))
(x^2 + 9y^2 - 4z^2 + 2x(-3y) + 2x(2z) + 2(-3y)(2z))
