Given that x= 3a+ 5/a+2. For what value of a is x not defined??
since division by zero is not defined, when a = -2, x is undefined
To determine the value of 'a' for which 'x' is not defined, we can observe the expression x = 3a + 5/a + 2 and identify any values of 'a' that would result in the division by zero, as division by zero is undefined.
In this case, we have a denominator of (a + 2). To find values of 'a' that would make the denominator equal to zero, we need to set (a + 2) equal to zero and solve for 'a'.
a + 2 = 0
a = -2
Therefore, when 'a' equals -2, the denominator becomes zero, which makes the expression x undefined.
