Find all numbers for which the rational expression is undefined. If the rational expression is defined for all real​ numbers, so state.

x/x+6

Type the values for which the rational expression is undefined.

Answer 1

Find all numbers for which the rational expression is undefined. If the rational expression is defined for all real​ numbers, so state. x/x+6

Type the values for which the rational expression is undefined.

You are not allowed to divide by zero. So, what makes the denominator equal to zero? Set it equal to zero and solve for x, that is what would make the rational expression undefined.

1. x + 6 = 0, subtract 6 from both sides, X = 6
