Maximum and Minimum Value Word Problems - Quadratic Equations

This algebra video tutorial explains how to solve word problems that asks you to calculate the maximum value of a function or the minimum value of a quadratic equation. The first problem asks you to determine the number of items a company must produce / sell to maximize the profit. The second question asks you to determine how long it takes for a ball to reach its maximum height as well as determine the maximum height. This is a typical projectile motion problem found in physics.

When the ad for the video is about not finding math help but magically here it is, only to receive the help after I skip the ad

I don't care what anyone says u have got to be the best teacher like seriously i think the only reason i pass is u.... no matter how many time or ways i search a question no, one explains it well or if they do they dont explain it in a general form i always end up back on ur video for chemistry physics and math
KEEP DOING WHAT YOU'RE DOING U ARE AWSOME THANK YOU FOR HELPING OTHERS❤️❤️❤️

MR. Organic Chemistry Tutor, once again this is an awesome video/lecture on finding The Maximum and Minimum Value of a Quadratic Equation. These are excellent problems that leads directly into Calculus One.

Thank you for making this easier to understand. My professor makes this harder than it is.

I have been up all night looking for a SAT test prep channel that is current. Thank you Jesus I found this channel!!!

[ShurooqFadhil-lxfp]

you are awesome I really like the way you explain the problem, you make it super easy, thanks.

[abigailb]

YES! Ive been looking for this forever thank u!

[btutohm]

respected sir, can you please help me with this question : A ball is projected with speed u at an angle
θ
to the horizontal. The range R of the projectile is given by
R
=
u
2
sin
2
θ
g

for which value of
θ
will the range be maximum for a given speed of projection? (Here g= constant

how do you find the amount of time it takes for something to get to its max height or how long it takes for something to hit the ground

I thought b was the second coefficient not the first..
