Question

Помогите решить уровнении. (6х-1)(6х+1)-4х(9х+2)=-1

Answer 1

(6x - 1)(6x + 1) - 4x(9x + 2) = - 1
36x² - 1 - 36x² - 8x = - 1
- 8x = - 1 + 1
- 8x = 0
x = 0

Answer 2

$(6x - 1)(6x + 1) - 4x(9x + 2) = - 1 \\ {6x}^{2} - 1 - 36x - 8x + 1 = 0 \\ {6x}^{2} - 44x = 0 \\ 2x( x - 22) = 0 \\ 2x = 0 \\ x = 2 \\ x - 22 = 0 \\ x = 22$
