The specified function's vertex form is
If a quadratic equation is written in the form
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
<h3>What is a perfect square polynomial?</h3>If a polynomial p(x) can be written as:
where f(x) is also a polynomial, then p(x) is called as perfect square polynomial
For the considered case, the polynomial specified is;
- Case 1: Converting to vertex form
Thus, the vertex form of the considered polynomial is
- Case 2: Converting to standard form
Standard form of a quadratic polynomial is
Thus, we get: the considered polynomial in standard form as:
- Case 3: Factoring the first two terms of polynomial
- Case 4: Forming a perfect square trinomial
The considered polynomial has only two terms, therefore, its not a trinomial.
Thus, the specified function's vertex form is
