Question

Which value will result in the expression (b+2)/(2b+4) being nor defined?

Answer 1

b = -2

Explanation:

Pre-Solving

We are given the following expression:

`(b+2)/(2b+4)`

And we want to find which value of b that will make the expression undefined.

This means we will find the value of b that will make the denominator equal 0, because if the denominator of a fraction is 0, it means that the fraction is undefined.

Solving

So, make 2b + 4 equal to 0.

2b + 4 = 0

Subtract 4 from both sides.

2b = -4

Divide both sides by b.

b = -2

So, if b is equal to -2, that will make the denominator 0, so it'll make the expression undefined.
