Question

N = (x + 3) (x + 2) + (x - 3) (x - 2) – 2x2 URGENTE ES PARA MI EXAMEN

Answer 1

Respuesta:

N = 12

Explicación paso a paso:

N = (x + 3)(x + 2) + (x - 3)(x - 2) – 2x²

N = (x² + 3x + 2x + 6) + (x² - 3x - 2x + 6) – 2x²

N = (x² + 5x + 6) + (x² - 5x + 6) – 2x²

N = x² + 5x + 6 + x² - 5x + 6 – 2x²

N = 2x² + 12 – 2x²

N = 12
