Answer 1

1 1
--- - ---
12 x

Answer 2

It may be easier to treat the numerator and denominator as separate terms first.
\[\left(\begin{matrix}1 \\ 144\end{matrix}\right) - \left(\begin{matrix}1 \\ x^{2}\end{matrix}\right)\]
and \[\left(\begin{matrix}1 \\ 12\end{matrix}\right) + \left(\begin{matrix}1 \\ x\end{matrix}\right)\]

Answer 3

You have learned that in order to perform adding or subtracting with fractions, you need to make sure both they have common denominators right? So first (treating them separately), make them have the same denominator.

Answer 4

Then there will be 2 equations\[\left(\begin{matrix}x^{2} - 144 \\ 144x^{2}\end{matrix}\right)\]
and
\[\left(\begin{matrix}x+12 \\ 12x\end{matrix}\right)\]

Answer 5

Since those 2 are separated by a division sign, it means the same thing as the numerator multiplied by the reciprocal of the denominator. Simplify.
