How do you simplify #(r+6)/(4^2-r-6)# and state the restrictions?
I assume your question is
Let's Factorise the
The Denominator is
We can use Splitting the Middle Term technique to factorise this.
It is in the form
To split the middle term, we need to think of two numbers
After Trial and Error, we get
So we can write the denominator as
The Denominator can be written as
The expression we have been given is
After the denominator was factorised, the Expression can now be written as :
