$lim_{x \to 8} \frac{6 x^{3} + 3 x^{2} \cdot (8 x) + 8}{2 x^{3} - 3 x^{2} - 10 x + 2}$

Step 1

Split the limit using the Limits Quotient Rule on the limit as $x$ approaches $8$ .

$\frac{lim_{x \to 8} 6 x^{3} + 3 x^{2} \cdot (8 x) + 8}{lim_{x \to 8} 2 x^{3} - 3 x^{2} - 10 x + 2}$

Step 2

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $8$ .

$\frac{lim_{x \to 8} 6 x^{3} + lim_{x \to 8} 3 x^{2} \cdot (8 x) + lim_{x \to 8} 8}{lim_{x \to 8} 2 x^{3} - 3 x^{2} - 10 x + 2}$

Step 3

Move the term $6$ outside of the limit because it is constant with respect to $x$ .

$\frac{6 lim_{x \to 8} x^{3} + lim_{x \to 8} 3 x^{2} \cdot (8 x) + lim_{x \to 8} 8}{lim_{x \to 8} 2 x^{3} - 3 x^{2} - 10 x + 2}$

Step 5

Move the term $3 \cdot 8$ outside of the limit because it is constant with respect to $x$ .

Step 12

Move the term $3$ outside of the limit because it is constant with respect to $x$ .

$\frac{6 {(lim_{x \to 8} x)}^{3} + 3 \cdot 8 {(lim_{x \to 8} x)}^{2} \cdot lim_{x \to 8} x + 8}{2 {(lim_{x \to 8} x)}^{3} - 3 lim_{x \to 8} x^{2} - lim_{x \to 8} 10 x + lim_{x \to 8} 2}$

Step 13

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

$\frac{6 {(lim_{x \to 8} x)}^{3} + 3 \cdot 8 {(lim_{x \to 8} x)}^{2} \cdot lim_{x \to 8} x + 8}{2 {(lim_{x \to 8} x)}^{3} - 3 {(lim_{x \to 8} x)}^{2} - lim_{x \to 8} 10 x + lim_{x \to 8} 2}$

Step 14

Move the term $10$ outside of the limit because it is constant with respect to $x$ .

Step 15

Evaluate the limit of $2$ which is constant as $x$ approaches $8$ .

$\frac{6 {(lim_{x \to 8} x)}^{3} + 3 \cdot 8 {(lim_{x \to 8} x)}^{2} \cdot lim_{x \to 8} x + 8}{2 {(lim_{x \to 8} x)}^{3} - 3 {(lim_{x \to 8} x)}^{2} - 10 lim_{x \to 8} x + 2}$
