Find the nonpermissible replacement for bin

this expression.

b2/5b + 5

b ≠ - 1

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that b cannot be.

solve

5b + 5 = 0 (subtract 5 from both sides)

5b = - 5 (divide both sides by 5)

b = - 1 ← excluded value
