Penjelasan dengan langkah-langkah:
Rumus mencari nilai limit tak hingga bentuk akar kuadrat:
[tex] \boxed{\lim\limits_{x \to \infty } \sqrt{ {ax}^{2} +bx + c} - \sqrt{ {px}^{2} +qx + r}}[/tex]
Dengan ketentuan:
Penyelesaian:
[tex] \lim\limits_{x \to \infty } \sqrt{ {x}^{2} - 2x + 3} - (x + 3)[/tex]
[tex]\lim\limits_{x \to \infty } \sqrt{ {x}^{2} - 2x + 3} - \sqrt{ {(x + 3)}^{2} } [/tex]
[tex] \small\lim\limits_{x \to \infty } \sqrt{ {x}^{2} - 2x + 3} - \sqrt{{x}^{2} + 6x + 9} [/tex]
[tex] \: \: \: \: \: \: = \frac{ - 2 - 6}{2 \sqrt{1} } [/tex]
[tex] \: \: \: \: \: \: = \frac{ - 8}{2 \times 1} [/tex]
[tex] \: \: \: \: \: \: = \frac{ - 8}{2} [/tex]
[tex] \: \: \: \: \: \: = - 4[/tex]
