En resumen
(x - y)(x - y) = x²–xy + y² (x + 5) (x - 6) = x² + x–30 (x + 6)(x–4) = x² + 2x–24 (x–3)(x + 5) = x²–2x–15 (x–2)(x–2) = x²–4x + 4 (4x–3y)(2x + 5y) = 8x²–xy–15y² (5x–4x)(3x–2y) = 15x²–14xy + 8y².
(x - y)(x - y) = x²–xy + y²
(x + 5) (x - 6) = x² + x–30
(x + 6)(x–4) = x² + 2x–24
(x–3)(x + 5) = x²–2x–15
(x–2)(x–2) = x²–4x + 4
(4x–3y)(2x + 5y) = 8x²–xy–15y²
(5x–4x)(3x–2y) = 15x²–14xy + 8y².
