@byTundrah they square of it's value will still be positive... but when you factor the "perfect square" the value will be negative inside the parenthesis squared.
dude thank u so much. i totally forgot how to find the vertex and tomorrows my exam but so its the h and k on the vertex form. thanks dude! so i just gotta convert to vertex form and w.e the h and k is, is the vertex
It isn't (9/2)^2, it is (3/2)^2, which ends up being (9/4). The writing is small, so I apologize for that. But, when you factor that 3 out of the first 2 terms, the "new b value" is now 3.
why do I have to go through sooo much bullshit, I mean, I don't want to be a mathematician so why do I have to learn this crap at school that I'll never use again in my life? Besides that, thx man, I finally understood this bulshit from your help.
I feel your pain ... on the other hand, are you going to be a poet? a historian? a writer? a doctor? a geologist? if not - then why learn anything? Learning math helps you learn other things faster and with greater depth. It really is a fascinating subject and I hope you grow to enjoy it :)
@dangarbo10 math is stupid... unless you realize it's responsible for practically everything in life... but why would that be worth learning? This generation sucks.
@Leeches93 why not learn math? your a human being you should know how the world works instead of letting ppl like scientists do all the work for you. dont be a passenger in life's plane...be the steward
True - however, how would we know that the x-value of the vertex is -b/2a without the quadratic formula? - and how would we know the quadratic formula without completing the square? Completing the square may be tedious, but it helps students with computation and comprehesion.
and thats mathtastic:) thanks this helped a lot!

example y=x2+10x-12
y=(x2+10x......)-12......=
y=(x2 half of 10 is 5 then 5mult 2 times (5)2=25
fil the blanks
y=(x2+10x+25)-12+25=
Y=(x+5)(x+5)13final anwser y=(x+5)2+13 vertex form the 2nd power
