En resumen
1. (5x + 8) + (7x - 13) = 5x + 8 + 7x - 13 = 12x - 5 2. ( - 2x³ + 5x² - 12x + 6) – (4x³ + 4x² - x + 3) = - 2x³ + 5x² - 12x + 6 - 4x³ - 4x² + x - 3 = - 6x³ + x² - 11x + 3 3. (3x)(4x + 1) + 7x = 12x² + 3x + 7x = 12x² + 10x 4. (x + 4)(x + 7) = x² + 7x + 4x + 28 = x² + 11x + 28 5.
1. (5x + 8) + (7x - 13) = 5x + 8 + 7x - 13 = 12x - 5
2.
( - 2x³ + 5x² - 12x + 6) – (4x³ + 4x² - x + 3) = - 2x³ + 5x² - 12x + 6 - 4x³ - 4x² + x - 3 = - 6x³ + x² - 11x + 3
3.
(3x)(4x + 1) + 7x = 12x² + 3x + 7x = 12x² + 10x
4.
(x + 4)(x + 7) = x² + 7x + 4x + 28 = x² + 11x + 28
5.
(x - 2)(x² + 2x + 4) = x³ + 2x² + 4x - 2x² - 4x - 8 = x³ - 8.
