Question

(X-2).(x-3)-[(x-4).(x-5)] Me ajuda a resolver ai galera!!!

Answer 1

(x - 2) * (x - 3) - (x - 4) * (x - 5) = 0
(x² - 3x - 2x + 6) - (x² - 5x - 4x + 20) = 0
x² - 5x + 6 - x² + 9x - 20 = 0
4x - 14 = 0
4x = 14
x = 14/4
x = 3,5

Answer 2

(x-2).(x-3) - [(x-4).(x-5)] = 0
x² - 3x - 2x + 6 - [x² - 5x - 4x + 20] = 0
x² - 5x + 6 - x² + 9x - 20 = 0
9x - 5x = + 20 - 6
4x = 14
x = 14/4
x = 3,5 ou 7/2
