Sorry a bit confused here ... can someone help me understand..
Given that (x^3+4x^2+4x)/x =9 , what is x?
x * (x^2+4x+4)/
------------------------ = x^2+4x+4 ==> Why is this wrong??
x
Why is that I cannot take x outside in the numerator as a common factory and cancel it with the x in the denominator.
There are some rules around inequalities with respect to potential negative variable.
