Algebra-2

1. Factorize the denominator:

.

So .

The numerator can be factored as .

Thus, . For , this simplifies to .

2. Vertical Asymptote:

Vertical asymptotes occur where the denominator is zero and the numerator is not zero at the same point.

Setting the denominator equal to zero gives  or , so  and .

When , the factor  cancels out.

When , the denominator is zero and the numerator
