How do you algebra? This factoring is destroying my brain molecules, & It's really difficult. Questions in comments.

Welcome back!
OpenStudy (sand-lock53):
Hello!
OpenStudy (3mar):
As you know...
Is there any factor can you take before factor them?

I don't think there are any
OpenStudy (3mar):
Ok
Next to that: direct factorization
OpenStudy (3mar):
Go ahead
OpenStudy (3mar):
This depends on your experience in factorization!
OpenStudy (sand-lock53):
what do I do differently this time?

Just a little big number at q^2, no more
OpenStudy (3mar):
The same roles, the same sequence
OpenStudy (eliesaab):
You can expand all the choices and see which one matches
OpenStudy (3mar):
This is the hard way
OpenStudy (eliesaab):
\[
(2 q-7) (6 q+2)=12 q^2-38 q-14
\]

Does this match?
OpenStudy (eliesaab):
I know it is the hard way, but it will show what is going on
OpenStudy (sand-lock53):
so, if i wanted to try the answer A, I'd have to do (2*-7) + (6*2)?
OpenStudy (eliesaab):
\[
(3 q+7) (4 q-2)=12 q^2+22 q-14
\]
OpenStudy (eliesaab):
Does this one match?

I think it is not the right one
the middel term will be 4q-42q=-38q
match?
OpenStudy (eliesaab):
and so on
OpenStudy (3mar):
I am talking about A
OpenStudy (eliesaab):
\[
(3 q+2) (4 q-7)=12 q^2-13 q-14
\]
How about this one?
OpenStudy (3mar):
I think I got it
It will be
\[(3q+2)(4q-7)\]

What do you think?
OpenStudy (3mar):
Yes, correct one!
OpenStudy (sand-lock53):
Hold on, I'm confused
OpenStudy (sand-lock53):
How did you get the middle term?
OpenStudy (3mar):
Easy
