En resumen
(6x * 1)² + (8x - 3)(8x + 3) = (20x - 1)(5x + 4) 36x² + 12x + 1 + 64x² - 9 = 100x² + 80x - 5x - 4 100x² + 12x - 8 = 100x² + 75x - 4 12x - 8 = 75x - 4 12x - 75x = - 4 + 8 - 63x = 4 x = 4 / 63 x≈0. 06349.
Mejor respuesta
(6x * 1)² + (8x - 3)(8x + 3) = (20x - 1)(5x + 4)
36x² + 12x + 1 + 64x² - 9 = 100x² + 80x - 5x - 4
100x² + 12x - 8 = 100x² + 75x - 4
12x - 8 = 75x - 4
12x - 75x = - 4 + 8 - 63x = 4
x = 4 / 63
x≈0.
