What is the undefined value of:
(3b^2 + 13b + 4) / (b + 4)

• Algebra -

For what value of b would you be dividing by zero ?

• Algebra -

I don't understand your question since I don't know the value of b.

• Algebra -

the point of Reiny's question is to remind you that division by zero is undefined.

So, when b+4=0, the expression cannot be evaluated. That is, when b = -4, the expression is undefined.
