What is the excluded value of a/b-2

b = 2

hope this helps

To find the excluded value of the expression a/b - 2, we need to identify the value(s) of b that would make the expression undefined.

The expression a/b is undefined when the denominator (b) is equal to zero because division by zero is undefined in mathematics.

So, to find the excluded value, we need to solve the equation b = 0.

Therefore, the excluded value of a/b - 2 is when b equals zero.

To find the excluded value of a rational expression, we need to identify any values of the variable that would result in the expression being undefined. In the case of the expression (a/b) - 2, the only potential source of undefined values is the denominator, which is b.

The expression (a/b) - 2 would be undefined if the denominator, b, is equal to zero. Dividing by zero is not possible in mathematics and leads to an undefined result. Therefore, the excluded value in this case is when b = 0.

To summarize, the excluded value for the expression (a/b) - 2 is when b = 0.

it's excluded because you cannot divide by 0. When b=2, b-2 = 0.
