Question

p^3 - 5p divide by p^2 - 16
The rational express is not defined for p= ?

Answer 1

\[p \ne 4\]

Answer 2

You cannot divide by zero. So p^2-16 cannot equal zero


If it were zero, then p^2-16 = 0. Solve for p to get p = 4 or p = -4


So the rational expression is not defined for p = 4 or p = -4

Answer 3

also p not = -4
