Question

Find the nonpermissible replacement for y in the expression n^2/2n+8

Answer 1

The nonpermissible replacement of the variable n is -4

Explanation:

The nonpermissible replacement of the variable in a certain expression is the value of the variable that will make the denominator of the expression zero.

The expression
`(n^2)/(2n+8)` has the denominator
`2n+8.`

This denominator cannot be equal zero, thus,

`2n+8\\eq 0,\\ \\n\\eq -4`.
