Bonjour, Quelqu’un peut m’aider à faire cette exercice de math svp ! Merci.

Hello

2x + 3 = 5x - 2

2x - 5x = -2 - 3

-3x = -5

x = 5/3

(3x-1)² = 0

3x - 1 = 0

3x = 1

x = 1/3

( 2x + 5/7 ) ² = 0

( 2x + 5/7 ) = 0

2x = -5/7

x = -5/14

x² - 2 = ( x - 1 ) ( x + 3 )

x² - 2 = x² + 3x - x - 3

x² - x² - 3x + x = 2 - 3

- 2x = -1

x = 1/2
