Question

For which value(s) of x will the rational expression below be undefined? Check all that apply

Answer 1

Given:

`((x+3)(x+6))/(x+7)`

Required:

We need to find the value of x that makes the given expression is undefined.

Step-by-step explanation:

Recall that a rational expression is undefined when the denominator is equal to zero.

The denominator of the given expression is x+7.

Equate it to zero.

`x+7=0`

Subtract 7 from both sides of the equation.

`x+7-7=0-7`
`x=-7`

Final answer:

`x=-7`
