Question 170497: Choose values of x to show that 2x^2-32/x-4 does not simplify to 2x-8. Then, simplify it correctly.
I simplified it and got that the correct answer is 2x+8. I do not know how to choose values of x to show that 2x-8 is incorrect.
Thank you for any help you can provide. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Choose values of x to show that 2x^2-32/x-4 does not simplify to 2x-8.
------
Assume [2x^2-32/x-4] = [2x-8]
Test x = 0
You get [(0-32)/(0-4)] = [0-8]
or [-32/-4] = [-8]
or 8 = -8 , which is wrong.
----------------------------
This shows that the assumed equality is not true.
