Решите уравнения

1) х=в числителе 8 х+36 в знаменателе х+13

2) (х-3) (х-4) (x-5) = (x-2) (x-4) (x-5)

1) x = (8x+36) / (x+13)

x (x + 13) = (8x + 36), (x + 13) ≠ 0

x² + 5x - 36 = 0

x=-9, x=4

2) (x-3) (x-4) (x-5) = (x-2) (x-4) (x-5)

(x-3) (x-4) (x-5) - (x-2) (x-4) (x-5) = 0

(x-4) (x-5) ((x-3) - (x-2)) = 0

(x-4) (x-5) (-1) = 0

(x-4) (x-5) = 0

x-4=0, x-5=0

x=4

x=5
