Question

Пр. каких значениях переменной алгебраическая дробь не имеет смысла? x+3/x(x-3) ?????

Answer 1

Дробь не имеет смысла, когда знаменатель =0, т. е. при х=0 и х=3

Answer 2

Algebraic Fractions and Undefined Values

An algebraic fraction does not have a defined value when the denominator equals zero. In the given expression x + 3 / (x(x-3)), the values of x for which the expression is undefined can be determined by setting the denominator equal to zero and solving for x.

The expression is undefined when the denominator, x(x-3), equals zero. Therefore, the values of x for which the expression is undefined are x = 0 and x = 3.

This means that when x is equal to 0 or 3, the given algebraic fraction does not have a defined value.

It's important to note that these values are excluded from the domain of the function to ensure that the expression remains defined and meaningful
