Question
use the expression \\(\frac{x - 6}{x + 4}\\).
how many excluded value(s) are there?
🆕 New Concept Discovered: Excluded Values of Rational Expressions
Values that make the denominator zero.
Step 1: Identify the denominator
An excluded value is any input that makes the denominator of a fraction equal to zero, because division by zero is undefined.
For the expression:
$$ \frac{x - 6}{x + 4} $$
The denominator is:
$$ x + 4 $$
Step 2: Set the denominator to zero
To find the excluded values, set the denominator equal to zero and solve for \( x \):
$$ x + 4 = 0 $$
$$ x = -4 $$
There is only \( 1 \) value of \( x \) (which is \( -4 \)) that makes the denominator zero.
