Find any real numbers for which the rational expression is undefined. x-8/x-9
The rational expression x-8/x-9 is undefined when the denominator, x-9, is equal to zero. Therefore, when x equals 9, the expression is undefined.
The rational expression (x-8)/(x-9) is undefined when the denominator, which is x-9, is equal to zero. To find the values of x for which the expression is undefined, we can set the denominator equal to zero and solve for x.
x - 9 = 0
Adding 9 to both sides:
x = 9
Therefore, the rational expression is undefined when x = 9.
To find the real numbers for which the rational expression (x-8)/(x-9) is undefined, we need to consider the values of x that make the denominator equal to zero.
In this case, the denominator (x-9) becomes zero if x = 9.
Therefore, the rational expression (x-8)/(x-9) is undefined for x = 9, as dividing by zero is not defined in mathematics.
