Question

How do I simplify this complex rational expression?

Answer 1

`(23x+3)/(20(x+1))`

Explanation:

Separate the fractions into a more readable format.

Factorise the denominators of all the fractions where possible. For
`x^2-1` apply DOTS ==> Difference of two squares*

Simplify the fractions.

I wrote out my working so I hope that helps :>>

*Difference of two squares is a method of factorising the sum of two squares, where one of them is negative.
`a^2-b^2 = (a-b)(a+b)`
