  1. Do not ping the Moderators, unless someone is breaking the rules.
  2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
  3. Do not ping other members randomly for help.
  4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

+close
Feel free to nominate the person for helper of the week in #helper-nominations
If you're happy with the help you got here, and the server overall, you can contribute financially as well:

1x for the 2nd space

howdu get that

1 second.

You know the method?

#

Of factorising.

#

Let me show you my notes.

modest perch
#

okay ty

modest perch
#

3x * x --> 3x^2

#

+2

cosmic sluice
#

Give me a second.

modest perch
#

okie

cosmic sluice
#

I forgot how to do it..

modest perch
#

sure😭

**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.

**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).

It's also not very helpful when you clearly cannot recall.

some1 said u don't need 7x cause we dk what x is

modest perch
distant mural
modest perch
#

7x/2 or like 7 times x ?

distant mural
#

No, I'll explain.

#

There's a really nice trick here.

#

Do you know how to factor expressions in the form x^2+ax+b?

modest perch
#

nah

#

sorry

distant mural
#

Hmm.

#

So, you can't factor x^2+5x+6, for example?

modest perch
#

u could

#

(x+1)(x+6) but idk bout that 5x

distant mural
#

Okay, well, I'll teach you the method for x^2+ax+b first, then for ax^2+bx+c.

#

Are you alright with that?

modest perch
#

no sorry

distant mural
#

Ok...

#

What did you make a help post for then...?

modest perch
#

for the help

#

Idk

modest perch
#

what ax means

distant mural
#

a is a constant, as well as b and c.

#

It is just a generalized form of the types of quadratics.

#

So for example, x^2+5x+6 is classified under x^2+ax+b.

modest perch

#

Since it doesn't have a term with leading coefficient that isn't 1.

modest perch
#

canu just go thru this pls

# modest perch canu just go thru this pls

Okay, but:

  1. Someone already gave the answer, so its pointless.
  2. I can clearly tell you don't understand how to do this, so I feel it's better off me teaching you in general.

nop

#

sorrry

distant mural
#

The difference between x^2+ax+b and ax^2+bx+c is the leading term.

#

The former has leading coefficient 1; the latter can have any leading coefficient.

modest perch
#

I don't get any of that

distant mural
#

Do you know what a leading coefficient is?

modest perch
#

nop

distant mural
modest perch
#

nop

#

sory

#

sorry

distant mural
#

Okay.

modest perch
#

I understand it now tho

#

thanks

distant mural
#

Well, the coefficient is the number next to a given variable.

distant mural
#

Explain it to me.

modest perch
#

I get it

#

cause x times x is x^2 cause u dk what x is

distant mural
#

Huh?

modest perch
#

n the brackets multiply each other

modest perch
distant mural
#

Yeah, that's a start.

distant mural
modest perch
#

u get the answer ?

distant mural
modest perch
#

thanks so much

distant mural
#

How would you get the answer?

modest perch
#

so basically

#

3x is alr there

#

so u need it to be ^2

#

so u put 1x cause x times x make x^2

#

then the +2 is fine

#

so u put a 1

#

but then like, what bout 7x ?

distant mural
#

Good.

distant mural
#

I'll show.

modest perch
#

oki

distant mural
#

(3x+1)(x+2)=3x^2+6x+x+2=3x^2+7x+2.

#

You know how to distribute, right?

modest perch
modest perch
#

whats dat

modest perch

am lost

#

I got the answer so it doesn't matter tho right ?

distant mural

okokokokok

distant mural
modest perch
#

noninonooo

#

don't show me that

distant mural
#

Why?

modest perch
#

it's too much

#

canu teach error intervals instead pls ?

distant mural
#

What?

modest perch
#

nah ac

#

do u know indicies ?

#

7x7 / 7x7x7x7x7

is 7^ 2/5 ? or -2/-5 ?

distant mural
#

Do you know your exponent laws?

modest perch
#

I got it now ty

modest perch
#

so it's 7^-3

#

@modest perch still need help

yeh a lil
