а)17x - x^2 = 0x^2 - 17x = 0x(x - 17) = 0
x = 0 или x = 17
б)36x^2 = 49x^2 = 49 / 36x = ±√(49 / 36)x = ±√(49) / √(36)x = ±7 / 6
Ответ: а) x = 0 или x = 17, б) x = ±7 / 6
а)
17x - x^2 = 0
x^2 - 17x = 0
x(x - 17) = 0
x = 0 или x = 17
б)
36x^2 = 49
x^2 = 49 / 36
x = ±√(49 / 36)
x = ±√(49) / √(36)
x = ±7 / 6
Ответ: а) x = 0 или x = 17, б) x = ±7 / 6
