Minta tolong dong. Ini gimana ngerjain nya. 49, 50. Tolong di bantu yaa.. Nanti di kumpulin soalnya

49) Lim (x^3 - 2x^2 + x)/(x^2 - 2x)
= Lim x(x^2 - 2x + 1)/x(x - 2)
= Lim (x^2 - 2x + 1)/(x - 2)
= (0 - 0 + 1)/(0 - 2)
= -1/2

50) Lim (x^2 - 16)/(x - 4)
= Lim (x + 4)(x - 4)/(x - 4)
= Lim (x + 4)
= 4 + 4
= 8
