mandre · Answer

$$limit_{x \rightarrow \infty}\frac{ -14x }{ 2+2x }$$
Is that the first one?

mandre · Answer

$$limit _{x \rightarrow \infty}[(\frac{ -14x }{ 2+2x }).(\frac{ 1/x }{ 1/x })]$$
You basically divide each term by the highest factor of x found in the denominator. 
$$limit _{x \rightarrow \infty}\frac{ constant }{ x ^{n} } = 0$$
