$lim_{x \to 1} \frac{x^{3} + 13 x^{2} + 24 x - 108}{x^{2} + 12 x + 35}$

Step 1

Split the limit using the Limits Quotient Rule on the limit as $x$ approaches $1$ .

$\frac{lim_{x \to 1} x^{3} + 13 x^{2} + 24 x - 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 2

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $1$ .

$\frac{lim_{x \to 1} x^{3} + lim_{x \to 1} 13 x^{2} + lim_{x \to 1} 24 x - lim_{x \to 1} 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 3

Move the exponent $3$ from $x^{3}$ outside the limit using the Limits Power Rule.

$\frac{{(lim_{x \to 1} x)}^{3} + lim_{x \to 1} 13 x^{2} + lim_{x \to 1} 24 x - lim_{x \to 1} 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 4

Move the term $13$ outside of the limit because it is constant with respect to $x$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 lim_{x \to 1} x^{2} + lim_{x \to 1} 24 x - lim_{x \to 1} 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 5

Move the exponent $2$ from $x^{2}$ outside the limit using the Limits Power Rule.

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + lim_{x \to 1} 24 x - lim_{x \to 1} 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 6

Move the term $24$ outside of the limit because it is constant with respect to $x$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - lim_{x \to 1} 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 7

Evaluate the limit of $108$ which is constant as $x$ approaches $1$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - 1 \cdot 108}{lim_{x \to 1} x^{2} + 12 x + 35}$

Step 8

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $1$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - 1 \cdot 108}{lim_{x \to 1} x^{2} + lim_{x \to 1} 12 x + lim_{x \to 1} 35}$

Step 9

Move the exponent $2$ from $x^{2}$ outside the limit using the Limits Power Rule.

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - 1 \cdot 108}{{(lim_{x \to 1} x)}^{2} + lim_{x \to 1} 12 x + lim_{x \to 1} 35}$

Step 10

Move the term $12$ outside of the limit because it is constant with respect to $x$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - 1 \cdot 108}{{(lim_{x \to 1} x)}^{2} + 12 lim_{x \to 1} x + lim_{x \to 1} 35}$

Step 11

Evaluate the limit of $35$ which is constant as $x$ approaches $1$ .

$\frac{{(lim_{x \to 1} x)}^{3} + 13 {(lim_{x \to 1} x)}^{2} + 24 lim_{x \to 1} x - 1 \cdot 108}{{(lim_{x \to 1} x)}^{2} + 12 lim_{x \to 1} x + 35}$

Step 12

Evaluate the limits by plugging in $1$ for all occurrences of $x$ .
