Find the Asymptotes y=((x-2)(x-1))/(x-2)

$y = \frac{(x - 2) (x - 1)}{x - 2}$

Step 1

Find where the expression $\frac{(x - 2) (x - 1)}{x - 2}$ is undefined.

$x = 2$

Step 2

The vertical asymptotes occur at areas of infinite discontinuity.

No Vertical Asymptotes

Step 3

Consider the rational function $R (x) = \frac{a x^{n}}{b x^{m}}$ where $n$ is the degree of the numerator and $m$ is the degree of the denominator.

1. If $n < m$ , then the x-axis, $y = 0$ , is the horizontal asymptote.

2. If $n = m$ , then the horizontal asymptote is the line $y = \frac{a}{b}$ .

3. If $n > m$ , then there is no horizontal asymptote (there is an oblique asymptote).

Step 4

Find $n$ and $m$ .

$n = 2$

$m = 1$

Step 5

Since $n > m$ , there is no horizontal asymptote.

No Horizontal Asymptotes

Step 6

Find the oblique asymptote using polynomial division.

Simplify the expression.

Factor $x^{2} - 3 x + 2$ using the AC method.

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $2$ and whose sum is $- 3$ .

$- 2, - 1$

Write the factored form using these integers.

$\frac{(x - 2) (x - 1)}{x - 2}$

Cancel the common factor of $x - 2$ .

Cancel the common factor.

$\frac{(x - 2) (x - 1)}{x - 2}$

Divide $x - 1$ by $1$ .

$x - 1$

The oblique asymptote is the polynomial portion of the long division result.

$y = x - 1$

Step 7

This is the set of all asymptotes.

No Vertical Asymptotes

No Horizontal Asymptotes

Oblique Asymptotes: $y = x - 1$

Step 8

Find the Asymptotes y=((x-2)(x-1))/(x-2)
