Nomor 2

$rm = displaystyle lim_{x to 1} ~dfrac {x²-1}{x-1}$

$rm = displaystyle lim_{x to 1} ~dfrac {(x-1)(x+1)} {x-1}$

$rm = displaystyle lim_{x to 1} ~(x+1)$

$rm = 1 + 1$

$rm = 2$

Nomor 3

$rm = displaystyle lim_{x to 0} ~dfrac {3x²-4x}{2x}$

$rm = displaystyle lim_{x to 0} ~dfrac {x(3x - 4)} {2x}$

$rm = displaystyle lim_{x to 0} ~dfrac {3x - 4}{2}$

$rm = dfrac {3(0) - 4}{2}$

$rm = -2$
