$lim_{x \to - \infty} \frac{3 (- \infty) - 5 {(- \infty)}^{3}}{1 + - \infty + {(- \infty)}^{3}}$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$lim_{x \to - \infty} \frac{3 (- \infty) - 5 {(- \infty)}^{3}}{1 + - \infty + {(- \infty)}^{3}}$
