    think of anything that would cause this to not exist. in otherwords... what does b have to be so that the denominator equals 0.

    k, i dont want to do that cause then you dont learn anything. but just remember that you can never divide by 0. so think of a number that you can plug in for 'b' that would give you a 0 on the bottom.

    close. but that would give you 5+5 which is 10.

    it may be easier to visualize if you just try to solve this equation: b+5 = 0. then you just solve for b.
