domain of (x^2+2x)/(x-1)

domain

\frac{x ^{2} + 2 x}{x - 1}

x < 1 or x > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

- 4 x^{2} + 12 x - 9

f (x) = \frac{10}{6 x - 30}

x - 1 + 2

f (x) = (x - 1)^{2}

f (x) = \frac{1}{2 - x ^{2}}

What is the domain of (x^2+2x)/(x-1) ?
The domain of (x^2+2x)/(x-1) is x<1\lor x>1
