Lim √25x² + 5x - 2 - (5x - 2)
x→~

Lim 25x² + 5x - 2 - (5x - 2)(5x - 2)
x→~ .. / √25x² + 5x - 2 + (5x - 2)

Lim 25x² + 5x - 2 - (25x² - 20x + 4)
x→~ .. / √25x² + 5x - 2 + 5x - 2

Lim 25x² + 5x - 2 - 25x² + 20x - 4
x→~ .. / √x² (25 + 5/x - 2/x²) + x (5 - 2/x)

Lim 25x - 6
x→~ .. / x (√25 + 5/x - 2/x²) + x (5 - 2/x)

Lim 25 - 6/x
x→~ .. / √25 + 5/x - 2/x² + 5 - 2/x

= 25 - 0 / √25 + 0 - 0 + 5 - 0

= 25 / √25 + 5

= 25 / 5 + 5

= 25 / 10

= 5/2
