Hi,
I need help with the problem below and would really appreciate an explanation as to how each step is done.
Thank you!
x - 1
4
___________
x-4
(x over 4 minus 1 divided by x minus 4)
$\displaystyle
\frac{\displaystyle\frac{x}{4}-1}{x-4}
$
That looks disgusting to work with. First, I'm just going to rewrite the top as a whole fraction:
$\displaystyle
=\frac{\displaystyle\frac{x-4}{4}}{x-4}
$
Now, this could be written as:
$\displaystyle
=\frac{x-4}{4} \div (x-4)
$
Can you see how that would equal $\displaystyle \frac {1}{4}$? If not, I'll try to explain further.
