The importance of h is that it represents the x-intercept, the lowest or the highest point of the graph of the expression. This is a very important factor when determining the turning points of parabolas
Answer:
Step-by-step explanation:
We are to factorize the expression 
completely. To do this, we will apply the expression below;
The expression can be rewritten as 
To factorize the expression, we need to first factorize 
first
The we will make the subject of the formula as shown;
This last result gives the expansion of the expression
