Can you find and ?

I would find the axial intercepts to graph this equation. For the x-intercepts make y=0 (the information above on factoring will be critical here) and vice versa for the y-intercept.

This one takes a bit of doing, but start by taking the coefficeint of x, half it, then square it, what do you get?

x^2 + 19x + 84 = 0

I know how to do in the quadratic formula because I learned from this forum.. but the others I don't know.... Im a learner, that seeing what people do, I learn how to do it.. thanks!!!!!

The above question summarises about 2 weeks worth of work. Sorry, but I have to ask - what is happening in your classroom? Are you getting notes from the teacher? Do you have a textbook? Are you asking your teacher for help? Are you learning anything?

Re: "I know how to do in the quadratic formula because I learned from this forum.. " Why haven't you learned this from your teacher? You must have been given some examples to follow ....?

MHF cannot be your surrogate teacher. MHF cannot do all your work. Surely you have some idea about the questions you're posting and can show some working ....? What have you tried with the above question?

Re: Quadratic problem...!

sir what is wrong with you... I just want to finish my virtual class..... this math is not going to help me in my future... that is why I wanted to finished..... I don't have any interest in learning it... I just want to pass it quickly so I can go to the class I like... AP MACROECONOMICS AND AP MICROECONOMICS>.... I hate the algebra and calculus..... That isn' for my future.... with all my respect to this forum, but I hate those subjects... every one in their life have the right to choose their path, but we also have STUPITS obligations to follow in school, so i choose how to skip those obligations in my way... if you are not dispose to help me, its ok with me... there are tons of sites that i can go in,( but I think this one is the best....) i just want ot pass that class... and graphs and quadratics are the worst thing in this world (FOR ME). I respect those people that are very smart like you in this forum, but I don't like you people giving me lessons i already know.... THNAK YOU FOR YOUR opinion in what i'VE TO BE DOING OR NOT, BUT I don't needed... :D \

All my regards.... and please don't bother me no more.. -.-"

Re: Quadratic problem...!

and if there is any qestion about what person am i.... IM THE LASIEST PERSON IN THE WORLD, BUT WHEN I WANT TO DO SOM,ETHING GOOD, THERE IS NO PEOPLE IN THE WORLD THAT CAN COMPETE WITH ME..... YOU CAN CHECK IT IN MY GRADES ATR SCHOOL... i GOT THE BEST STUDENT IN 9TH GRADE.... IM GOING TO 10TH WITH ALL CLASSES HONORS... AND LAST YEAR (9TH) i GOT STRAIGHT A'S :d

Re: Quadratic problem...!

It's not important that you have all classes honors, ... This forum wants to help, but it seems that if this forum helps you, you confirm you understand the exercice and afterwards you make a new topic with exactly the same kind of exercices and you're stuck again. Why is that? All the topics you have started deal with quadratic equations and functions and it's explained more then one time and it looks you don't get it after all this times. It's important to exercice and at least try making some exercices, not to let someone else do your work. So, are you able to solve quadratic equations now? Before you make a new topic have you already tried the exercices? ...

Re: Quadratic problem...!

I don't want to do it... I HATE QUADRaTICS... i know how to but i don't want to... I have to many clasess I like to do the one (obligated) I don't want.... so please I just need some help.. thanks!

Tough. Welcome to life.

You have to do quadratics because they appear everywhere. You really think you'll be able to do *economics* without understanding quadratic equations?

What a shame. If you don't show a willingness (and ability) to learn, it is unlikely you will recieve any help.

Re: Quadratic problem...!

everyone is free of choosing their path in life.. mine is thisone.. if you people are not in dissposal of helping me.. ok its ok with me... who knows tomorrow's day I can be your boss... and who knows if i'll be good or bad.... remember that this world is tiny, and we're all connected people.. :D bless ya. :D

What I have highlighted in red makes your attitude very clear. No help is given with an attitude like this. MHF is not here to do your wrok. Thread closed.
