Question

7n^2 - 14n^2 + 6n - 12

Answer 1

This is a solve for \(n\) correct?

Answer 2

Do you remember what I told you earlier in the morning about group factoring stuff?

Answer 3

Just factoring, I do but vaguely.

Answer 4

I know 7n^3-14n^2 is 7n^2

Answer 5

and 6n - 12 is 6

Answer 6

Yep!!!
So we distribute it out to
7n^2(n-2) + 6(n-2)

Answer 7

So, what is it?

Answer 8

(7n^3 - 2) (6n-2)?

Answer 9

Oop-
You made the same mistake last time too

Imagine it like x(7x^2) + x(6)

Answer 10

the x would be -2 right?

Answer 11

or 2 - n

Answer 12

Just put x as x for now
How would you un-distribute it
x(7x^2) + x(6) ---> _____
ab + ac

Answer 13

shoot, too many -s

Answer 14

(n-2) and (7n^2+6)

Answer 15

Yep~
(n-2)(7x^2 +6)

Answer 16
