Question

Rozwiaz rownanie x/(x-2) = ( x+2)/(x-1)

Answer 1

Rozwiaz rownanie x/(x-2) = ( x+2)/(x-1)  x          (x +2) ------- = -------- (x -2 )    (x -1)                      Zal. x -2 ≠0 oraz x -1 ≠ 0                                                   x ≠ 2    oraz   x ≠ 1 x(x -1) = (x-2)(x +2) x² -x = x² -4 x²-x -x² = -4 -x = -4      /:(-1)  x = 4
