Thanks so much! I've watched so many videos with no luck and thanks to you I finally understand this!

Thank you for actually teaching. My teacher handed us a worksheet and said "do it"

@zalapasha Yes you could...use the power rule to find the derivative. Set the derivative equal to zero and solve.

What would be the minimum area for the same problem?

The equation for the max = vertex also applies for the minimum, right?

This is off topic but what are you recording with?

Me too I forgot there is -b/2a hahahah:D Thank you for your video ;)

I totally forgot u could do this I always used completing the square much more work

[zalapasha]

thx, you could also use first derivative to solve that couldn't you?
