Question

Hi guys, help me
x^2+3x+2 for this equation how to find the possible x values?

Answer 1

First, factorize the equation. Can you do that?

Answer 2

Think what numbers when added equal 3 but when multiplied equal 2?

Answer 3

yes

Answer 4

So what numbers when added equal 3 BUT
when multiplied equal 2

Answer 5

_+_= 3

_*_= 2

Answer 6

Fill in the blanks

Answer 7

1,2 is correct?

Answer 8

Yes.

Answer 9

So now lets break down 3x
x^2+1x+2x+2

Answer 10

Now lets factor

Answer 11

x^2+1x then factor 2x+2

Answer 12

Are you having trouble @nroprstar

Answer 13

hi tell me more cleary yar..

Answer 14

\[x^{2}+1x+2x+2\]
\[x^{2}+1x \]
2x+2

Answer 15

What do we have in common (Letters or Numbers) in the following equation
\[x^{2}\]

Answer 16

-1 and -2

Answer 17

correct!

Answer 18

That is not the solution.

Answer 19

Is not?

Answer 20

Okay look...

\[x^{2}+1\]

factors as...
x(x+1)

Answer 21

little typo mean to post: \[x^{2}+1x\]

Answer 22

No,, I am trying to find eigen values in matrix...

Answer 23

k mathlegend... tell

Answer 24

2x+2
factors as what?
2(x+1)
right

Answer 25

My mistake, sorry. I probably was thinking of another topic.

Answer 26

So now we have
x(x+1)+2(x+1)

Answer 27

mm ok

Answer 28

All the outside numbers go in one set of parentheses and the inside go in another.

Answer 29

s

Answer 30

(x+2)(x+1)

Answer 31

That is your answer.

Answer 32

ya now I understood. thanks alot

Answer 33

No problem

Answer 34

so x=-2 or -1

Answer 35

@MathLegend they are asking for 'possible values of x'

Answer 36

if my explanation was correct and we are talking about the same topic, x would be -2 and -1

Answer 37

oh, well, okay.

Answer 38

Hold on. Let me get someone else's opinion.

Answer 39

Basically MathLegend and I are thinking about the same thing...

Answer 40

@experimentX

Answer 41

you cannot find the value of unknown from an expression.

Answer 42

you need equations ... f(x) = 0 or a system of equations..

Answer 43

Well, being what experimentX said.. then are you sure you were not supposed to just factor @nroprstar

Answer 44

ahh.. okay. I was thinking of something else then. http://www.themathpage.com/aprecalc/roots-zeros-polynomial.htm

Answer 45

I was looking of the values of x that would make the equation to zero.

Answer 46

Sorry, @nroprstar

Answer 47

They haven't given a right side so its not an equation, its an expression.

Answer 48

these people are good @pratu043 never doubt them. they are able to *solve* expressions <bows down>
