Answer 1

sorry its kinda long

Answer 2

lol it's the same thing use (b/2)^2

for EVEERYTHHING

on these questions.

Answer 3

see the thing is i dont know how to work these problems out because i missed school for 6 weeks because i was in the hospital

Answer 4

i'm sorry to hear that but we just did these like 3 times :/

Answer 5

do you know what the b values are here ?

Answer 6

no

Answer 7

3x^2+4x+____=1+_____

3(x^2+(4/3)x+____)=1+3(_____)

Answer 8

how do i figure that out

Answer 9

That was just factoring of the leading coefficient, 3.

Answer 10

ax^2+bx+c=0

Answer 11

they are all in that form

Answer 12

im sorry i really dont know

Answer 13

@DanJS

maybe your a better explainer than me

Answer 14

thanks for trying to help im so sorry

Answer 15

it's ok. im just hoping someone can make this go through your mind better. i can't teach

Answer 16

its just fine

Answer 17

We need this principle \((a+b)^{2} = a^{2} + 2ab + b^{2}\)
We have \(x^{2} + (4/3)x + Something\)
How do we decode that?

Answer 18

i have no idea i havent learned any f this i was in the hospital and out of scool for 6 weeks

Answer 19

Okay, it requires thinking. Look at that "need" thing I wrote above. Ponder its properties.

The first term is a perfect square.
The third term is a perfect square.
Can you build the second term, if you know only the 1st and 3rd terms?

\(x^{2} + 2nd\;Term + 16\)

What is the 2nd Term?

Answer 20

I DO NOT KNOW

Answer 21

Not good enough. Think about it. Reread both of the last posts and answer the question.

Answer 22

dont tell me its not good enough if i didnt learn it then i didnt learn it o there for i dont know it so no your answer isnt good enough you incompetent pig

Answer 23

I will tell you what I believe you need. Throwing your hands int he air is not good enough, by definition. Are you going to think about it or not? If you want to learn it and pass the exam, this requires thinking.

The first term is a perfect square, \(x^{2}\). It is a square of what?
The third term is a perfect square, \(16\). It is a square of what?

Answer 24

wow you really dont get it maybe you should explain things a little better before you criticize anyone else about not understanding something learn to actually help then be an a hole stop trying to get past my level you wont ever reach it boo boo

Answer 25

Not criticizing. I'm giving you the facts and I am showing you how to think about it.

If you want to control the engagement, you should consider paying for it.
Since you are here for free, you should listen, rather than give orders.

Answer my questions and you will learn. Go!

Answer 26

@boobear74

if you listen i guarantee this topic will be a lot easier

Answer 27

please listen.

Answer 28

its hard to do something if i dont know what the dude is talking about at all so please do tell ,e how im supposed to listen

Answer 29

you can ask questions about what he said. but don't call him a pig or what not..

Answer 30

you need to ask a real question, not "i don't know"

Answer 31

i did nothing was solved

Answer 32

no...you simply said "I don't know", but which part exactly?

Answer 33

The difficulty, here, is that you ASSUME you don't know what I'm talking about. In fact, you DO know. Let's try one question again. I think you CAN answer it.

The third term is a perfect square, 16. It is a square of what?

Answer 34

@boobear74

Do you still want help??
