Question

(x-3)2 – (x-4)2 = 3​

Answer 1

Respuesta:

( x -3)² - (x -4)² = 3

x = 5

Explicación paso a paso:

( x -3)² - (x -4)² = 3

(x -3)² = x² -2.3.x + 3² = x² -6x + 9

(x -4)² = x² -2.4.x + 4² = x² - 8x + 16

( x -3)² - (x -4)² = 3

x² - 6x + 9 - x² + 8x - 16 = 3

2x - 7 = 3

2x = 3+7

x = 10/2

x = 5

( x -3)² - (x -4)² = 3

(5 - 3)² - ( 5- 4)² = 3

(2)² - (1)² = 3

4 - 1 = 3

3 = 3
