TOLONGG LIMITT KELAS 11
Jawaban:
-6/5
Penjelasan drngan langkah-langkah:
[tex]\[ \lim_{x\to\infty}(5x - 2) - \sqrt{25 {x}^{2} - 8x + 2} \] \\ = \[ \lim_{x\to\infty} \sqrt{(5x - 2) {}^{2} } - \sqrt{25 {x}^{2} - 8x + 2 } \] \\ = \[ \lim_{x\to\infty} \sqrt{25 {x}^{2} -20x + 4 } - \sqrt{25 {x}^{2} - 8x + 2 } \] \\ = \frac{b - q}{2 \sqrt{a} } \\ = \frac{ - 20 - ( - 8)}{2 \sqrt{25} } \\ = \frac{ -1 2}{10} \\ = - \frac{6}{5} [/tex]
