A quadratic equation can be written in vertex form or 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.
A. factor the equation
b. graph the parabola
c. identify the vertex, minimum, or maximum of the parabola
d. solve the equation using quadratic formula
pls help I'm very lost

Wow, I have the exact same question. If someone would answer this please, it would help over millions of people.
Well, to factor an equation you need to use the standard form. To graph the parabola, you need to use the vertex form. You also need the vertex form to identify the vertex, minimum, or maximum of the parabola. To solve the equation using the quadratic formula, you need to once again use the standard form.
The standard form is y = ax + bx + c
The quadratic formula is x = -b +- square root of b^2 -4ac, then you divide everything except x by 2a.
A quadratic equation can be factored from y = ax + bx + c. So the standard form can be used for both (a) and (d) (answer choices).
The form/equation above is used to identify the vertex and identify the maximum and minimum of a parabola.
I hope this helps you all!

Oh, oops. I forgot to say the vertex formula can be used for both (answer choices) (b) and (c).
