Tolong bantu jawab no 11 dan 12 sama caranya ya

suku dua
maaf kalo salah

11) Lim (3x^5 + x^3 - 4x^2)/(8 - 7x^3 + 2x^5) . (1/x^5)/(1/x^5)
= Lim (3x^5/x^5 + x^3/x^5 - 4x^2/x^5)/(8/x^5 - 7x^3/x^5 + 2x^5/x^5)
= Lim (3 + 1/x^2 - 4/x^3) / (8/x^5 - 7/x^2 + 2)
= (3 + 0 - 0)/(0 - 0 + 2)
= 3/2

12) Lim x(3x - 1)^2)/(x^2 - 3x + 4)
= Lim x(9x^2 - 6x + 1)/(x^2 - 3x + 4)
= Lim (9x^3 - 6x^2 + x)/(x^2 - 3x + 4) . (1/x^3)/(1/x^3)
= Lim (9x^3/x^3 - 6x^2/x^3 + x/x^3) / (x^2/x^3 - 3x/x^3 + 4/x^3)
= Lim (9 - 6/x + 1/x^2) / (1/x - 3/x^2 + 4/x^3)
= (9 - 0 + 0)/(0 - 0 + 0)
= ~
