Question

Rezolvati ecuatia 10-2(x-1)^2=3(x-1)-(x-2)(2x+1) rezolvare completa .

Answer 1

2x + 24 - 6x + 3 = 5x + 9 2x - 6x - 5x = - 24 - 3 + 9 - 9x = - 18 x = 18 : 9 x = 2 b) 4x + 1 - 3x - 6 = 2x - 8 4x - 3x - 2x = - 8 - 21 + 6 - x = - 23 x = 23 c) 2x + 6 - 10 + 2x = 7x + 2 2x + 2x - 7x = - 6 + 10 + 2 - 3x = 6 x = - 6 : 3 x = - 2 d) 6x + 11 - 5x + 10 = 4x - 12 6x - 5x - 4x = -11 - 10 - 12 - 3x = - 33 x = 33 : 3 x = 3
