Completing the square to identify the max,min, vertex and axis of symmetry

www.freemathvideos.com We will learn how to graph a quadratic in vertex form and graph a quadratic in standard form by completing the square and rewriting the equation in vertex form. When the quadratic is in vertex form we learn how to identify the axis of symmetry and vertex. Then apply transformations to identify the new graph. Lastly we will learn how to write the equation of a quadratic given the vertex, a point or three points.
y = x^2 + 2x - 3

Your way of teaching is really helpful sir, not only for students even for teachers.

[@harmanrealestate]

Thank you so much, I've been stressing with this for so long and now completely understand - thank you

[@halladaas9915]

if the lenient term were -2x, would we consider the negative sign so that (b/2) becomes -1?

[@maryammaher167]

i love how you explained why certain procedures are done on the equation, better than memorizing the steps without grasping what they do, like fr tnx

[@m.ricc0305]

20 times better than my math teacher👍🏻

happy to help

[@sadiksarkar5314]

sir ,you are awesome ...I was amazed after seeing the steps it is so easy but I was just making it complicated ...tnx😊😊😊✌✌

Happy to be there for you Sadik

i cannot put in to words about how grateful I am for you thank you so much sir

Hi，teacher!Why the min or max point of the graphing of quadratic function can be found through the method of completing the square ？

[@brianmclogan]

because when you complete the square the quadratic is now in vertex form where the vertex is at (h,k)

[@h.renhwai2675]

thank for answers

Yo Dr. McLogan, why does College algebra have to be so difficult

[@ndeztech]

This is college algebra? I’m doing this in high school.

@@ndeztech you'll have to do it in college too unless you can test out

Don’t the signs switch when you take them out of the bracket?

[@brianmclogan]

only if factoring out a negative

There's a reason why Asians are better in math and it shows with how complicated you do this
