Question

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 listen 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 the quadratic formula.

I dunno why.

Answer 1

Oooooh, I see many others asked the exact same thing! 😮

Answer 2

I answered this same question 2 years ago, I copy and pasted the answer from that time, here it is:


a) clearly in standard form
b) I find the vertex form useful, since you immediately have one point and the axis of symmetry. All you need is another point and its reflection in the axis of symmetry and you should be able to sketch the graph
c) If you have to find the vertex, max/mins etc, what form contains the word vertex ??
d) The formula is defined according to a, b, and c of
ax^2 + bx + c = 0 . So what do you think?
