Question

P=x-2 ÷ x+1 for what value of x is P undefined​

Answer 1

x = - 1

Explanation:

P =
`(x-2)/(x+1)`

the denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.

x + 1 = 0 ( subtract 1 from both sides )

x = - 1

P is undefined when x = - 1
