Answer 7

x = 0.2

Answer 8

explanation: Assuming you meant (4x - 8) over (x² - 2x),
First factor each expressions. You will find some cancelling out.

(4x - 8) / (x² - 2x)
= 4(x - 2) / x(x - 2)

The x - 2 in numerator and denominator cancel, leaving you with

4/x <---ANSWER

Looking at the original expression, we don't want denominator to equal 0.
x² - 2x = 0
x(x-2) = 0
x = 0, 2

So your expression is undefined at x = 0, 2 <---- ANSWER
