Question

Evaluate the expression for the given value of the variable.  

 

4/over x^2-2x-3=

 

x=1

Answer 1

      4

-------------     at x = 1

x² - 2x - 3

 

 

      4

-------------

1² - 2(1) - 3

 

      4

------------- 

1 - 2 - 3

 

 

4/-4 = -1

 

Answer 2

Hello, thank you for taking the time to post your question!

We’re given the general form of the question and then asked to plug in the value x = 1 in order to simplify.

So that becomes

4 / (1^2 – 2(1) – 3)

= 4 / (1 – 2 – 3)

= 4 / (-4)

= -1

So the evaluated expression that it should be after here is -1

I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
