limit x-> ~ (3x-2) - √9x^2-2x+5 adalah.....

limit mendekati ~

lim (x-> ~) (3x - 2) - √(9x² -2x+5) =
= lim(x->~)  √(3x-2)² - √(9x² -2x +5)
= lim(x->~) √(9x²-12x + 4) - √(9x² -2x+5)
a= 9, b = -12 , p = 9 , q = -2

limit = (b- q)/ (2√a)
limit = (-12-(-2)) / (2√9)
limit = (-10)/ (2)(3) = -10/6 = - 5/3
