If a quadratic function is written in the form 

Then (h,k) is the vertex, and 'a' is a constant.
For instance 

has vertex at (2,3).
Also, an absolute function in the form 

has vertex at (h,k).
This means 

also has vertex at (1,3).

If we write out the expression √4√6/√3√2, then we get the solution to the surd as 2.
<h3>What is a surd?</h3>
A surd is an irrational number which is often shown as a square root. In this case, we have the value; √4√6/√3√2.
This is the same as; 2√6/√6. This now implies that we can cancel out the surd form which is shown as √6 hence the result of the expression is 2.
