tolong dijawab 2 soal ini yah makasih

16
lim(x->∞) √(9x²- 4x +2) - √(9x²)
a= p= 9
b = - 4
q = 0

limit=  b- q/ 2√a= (-4-0)/( 2√9) = - 4/6 = - 2/3

17.
limit (x->∞) √(4x+3) - √(16x² - 4x + 2)
limit (x-> ∞) √(16x²+24x + 9) - √(16x²- 4x + 2
a = p = 16
b =  24
q = -4

limit=   b - q/2√a = (24-(-4))/( 2)(√16)
limit=28/  8 = 7/2
