Bonjour pouvez vous faire c’est équation merci

Réponse :

(4x² - 24x + 36 = 0 => (2x - 6)² = 0 => 2x - 6 = 0 => x = 3

-5x² + 30x = 0 => -5x(x-6) = 0 => -5x = 0 => x = 0  ou x-6 = 0 => x = 6

(2x-1)(2x+1) = 0 => 2x-1 = 0 => x = 1/2 ou 2x+1 = 0 => x = -1/2

(3x+5)² = 81 => 3x+5 = -9 => 3x = -14 => x = -14/3

                   ou 3x + 5 = 9 => 3x = 4 => x = 4/3

Bonne soirée
