b = 2
b = - 2
none of the above

Answer 1

what will make the denominator 0?

Answer 2

so its b- 2?

Answer 3

If the denominator ends up being 0, it is not a valid solution, and it will be extraneous.

Answer 4

yea b = 2

Answer 5

because 2 - 2 gives u 0 and you can't divide

Answer 6

when 0 is the denominator

Answer 7

Note: \(\sf\Large\frac{x}{0}=undefined\)

while

\(\sf\Large\frac{0}{x}=0\)

Answer 8

So the denominator can not be 0, otherwise we don't get a solution.

So just set the denominator equal to 0. And you solve.
