What are the instructions for the posted problem?

its factoring diamond

yeah factor by grouping :)

6x^2 +5x -4
What are two numbers that multiply to -24 AND add to 5 ?

2?

i think e. e

ithink anyways i have the other side of it.. its (2x-1)( )

-1 * 1 = -1 so that is not it.

1 can multiply -4

no wait wat?? i need to find a number that can multiply by 4?

3x?

so its 3x-4?

Let's see if it works:
6x^2 +5x -4 = (2x-1)( 3x +4 ) ?? @chubbytots What do you think?

yep its right actually im answering a puzzle e. e

that's right @Directrix

\[3x^2-11x-20=\]

>>so its 3x-4?
I did not get that.

its 3x+4

for da first group and the second group is?

(2x-1)*(3x-4) multiplies to 6x^2 -11x + 4 which is not the given problem.

Okay, let's try that.

6x^2 -11x + 4=(2x-1)(3x+4)

(2x-1)*(3x+4) = 6x^2 -3x + 8x -4 = 6x^2 + 5x - 4.

thats da second question and da second question is \[3x^2-11x-20=(3x+4)( ? )\]

i mean third**

I only saw the first problem.

i need the third problem cuz this is a pzzle v. v

3x^2 -11x - 20 = (3x+4) * ( )
What times 3x is equal to 3 x^2 ?

4x+3?

3x^2 -11x - 20 = (3x+4) * (x )

3x times 4x = 12 x^2 -->doesn't work

is it positve 3?

3x times 3 = 9x.

yes

Oh, you mean ( x + 3) as the second factor?

yes

(3x+4) * (x + 3 ) = 3x^2 -11x - 20 ??
3x^2 + 9x + 4x + 12 Nope.

We could guess forever.

xDD i think lol and another one :O

i think its x-3?

4 times - 3 is not -20.

i mean 2?

i mean 5 sorry :o

4 times 5 is close but 4 times 5 does not equal -20

hmmmm

i think we need to make one of them a negative right?

Yes.

so-5?

Yes

its x-5?

3x^2 -11x - 20 = (3x+4) * (x - 5 )

That works.

yes

\[6x^2+11x-10=(2x+5)(?)\]

It's your turn to do this one. :) You come up with the factors, and I will check.

i'll be guessing dou

That's what I ended up doing because you didn't like factoring by grouping.

2x+1

lol actually this s factoring by grouping.. and i need to do factor diamond

its like two steps first is factoring by grouping and factoring diamond

That diamond thing is sophisticated guessing for me.

x. x so can we do factoring by grouping?

(2x+1)*(2x+5) = 4x^2 + 12x + 5 --> This is from your guess.

It didn't work.

2x-5?

I'm going to group.

is it 6x10?

6x10=60 ryt and wet going to make one of them a negative?

6 + 10 is not 11

15 and -4.

x^2 + 11x - 10 = x^2 + 15x - 4x - 10

5x+2?

This thread is so long that I have lost the problem.

(2x + 5) * ( 3x + 2)
That is my last factoring problem on this puzzle.

so its 3x+2?

3x-2?

6x^2 + 15x - 4x - 10 = 3x(2x + 5) - 2(2x + 5) = (2x + 5) * ( 3x - 2).
Right.

owoo that was brain storm >,<

The more of this stuff you do, the better you get. Except, I seem to be getting worse.

ohh yah sure cuz when im learning this i was lazy thats why i came up here >.<

What is the next factoring problem?

how abut this?
\[7x^2+13x-2=(x+2)(?)\]

xDD under the typing box thou
v
v
v
v
v

actually this factoring group so on this is the new lesson on our school e. e''''

and imto lazy about it

xDD uhh nope o. o

ohh well i better rap dis up cuz im gonna go early tommorow well thanks fo the help :)

Okay. See later on here.

ok byee
