Question

Решите уравнение (6х-2)2- 6х+2=0

(2х-3)2=2х-1

(если можно решение на фотографии) ​

Answer 1

№1

$(6x - 2)2 - 6x + 2 = 0$

$(6x * 2) + (-2 * 2) - 6x + 2 = 0\\12x - 4 - 6x + 2 = 0\\12x - 6x = -2 + 4\\6x = 2\\x = \frac{2}{6}$

$x = \frac{1}{3}$

№2

$(2x - 3)2 = 2x - 1$

$(2x * 2) + (-3 * 2) = 2x - 1\\4x - 6 = 2x - 1\\4x - 2x = 6 - 1\\2x = 5\\x = \frac{5}{2}$

$x = 2,5$
