30 POINTS PLEASE HELP I WILL MARK BRAINLIEST IF THERE IS NOT AN ACTUAL ANSWER IN YOUR COMMENT YOU WILL BE REPORTED a quadratic equation can be written in vertex form or in standard form sometimes one form is more beneficial than the other identify which form would be more helpful if you needed to do each task listed below and explain why factor the equation graph the parbola identify the vertex minimum or maximum of the parabola solve the equation using the quadratic formula

a. factor the equation

b. graph the parabola

c.identify the vertex,minimum or maximum of the parabola

d. solve the equation using the quadratic formula

Step-by-step explanation:

Below are suppose the be the questions:

A. factor the equation

B. graph the parabola

C. identify the vertex minimum or maximum of the parabola

D. solve the equation using the quadratic formula

Below are the answers:

Vertex form is most helpful for all of these tasks.

Let

.. f(x) = a(x -h) +k ... the function written in vertex form.

A) Factor:

.. (x -h +√(-k/a)) * (x -h -√(-k/a))

B) Graph:

.. It is a graph of y=x^2 with the vertex translated to (h, k) and vertically stretched by a factor of "a".

C) Vertex and Extreme:

.. The vertex is (h, k). It is a maximum if "a" is negative; a minimum otherwise.

D) Solutions:

.. The quadratic formula is based on the notion of completing the square. In vertex form, the square is already completed, so the roots are

.. x = h ± √(-k/a
