Question

n(n ‒ 3) + 2(n ‒ 3) = ( )(n ‒ 3)

That video didn't help me at all.

Answer 1

i don't think we can explain it better than the video. I think this has to be explained in person, ask your teachers or your parents :)

Answer 2

I don't have a teacher.

Answer 3

:(
where did you get this question then?

Answer 4

Plato and my dad won't help me either.

Answer 5

so you know PEMDAS?

Answer 6

Yes. I don't under stand the pulling the letters out... Why would I do that?!

Answer 7

ah..ok
firstly, they are not letters, they are letters which represent 'numbers'
and the pulling them out part..its just property of numbers, its a law of mathematics


do you know what 'factors' are?

Answer 8

No

Answer 9

well....you should have learn what factors are by now, judging by the question you posted.
there are a few simple concepts which you should be knowing in order to answer that question,
some of them are
representing numbers as letters
factors
distributive property of multiplication over addition

Khan academy is a good place to start

Answer 10

Whatever I just I quit.

Answer 11

well, thats upto you, but this is very basic math which you will actually need in life, even if you want nothing to do with math or science

Answer 12

I'm sure I won't need math to drive.

Answer 13

Just plug in the leading coefficients from the left side.
n(n-3)+2(n-3)=( ? )(n-3)

n(n-3)+2(n-3)=(n+2)(n-3)

Answer 14

The further explanation would be to distribute the leading coefficients and factoring from there.
