How do you find the derivative of y=(x^2 - 1) /( x+1)?

Oct 30, 2016

The derivative is $1$

Explanation:

Start by simplifying the function.

$y = \frac{\left(x + 1\right) \left(x - 1\right)}{x + 1}$

$y = x - 1 , x \ne - 1 \text{ } \to$ there will be a hole at $x = - 1$

We can now differentiate this using the power rule.

$y ' = 1$

Hopefully this helps!
