Question

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

Answer 1

Answer:

The value of the expression is $= \frac{1}{25}$

Step-by-step 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,

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

$= \frac{25+ 1 }{25}- 1$

$= \frac{26}{25} - 1$

$= \frac{26}{25} - \frac{25}{25}$

$= \frac{1}{25}$
