Question

Question 2: If x = -5, what is the value of
x^2+1
______ -1 ?
x^2

Answer 1

The value of the expression is
`= (1)/(25)`

Explanation:

The expression whose value is to be found is
`\frac{ {x}^(2) + 1 }{ {x}^(2) }- 1`

Also from the question, x=-5

Hence to find the value for the expression, we put x=-5 and simplify.

This implies that,

`\frac{ { (- 5)}^(2) + 1 }{ {( - 5)}^(2) }- 1`

`= (25+ 1 )/(25)- 1`

`= (26)/(25) - 1`

`= (26)/(25) - (25)/(25)`

`= (1)/(25)`
