so....have you done any factoring? have you covered factoring?

yes I have

ok
well.. let's start backwards
any ideas on say C) since is very simple \(\bf x^2-36\) ?

okay so I would explain this one by saying the square root of 36 is 6

yes, or that 36 is the square of 6
and thus it makes it a difference of squares

so that is showing work on factoring?

for C), yes

|dw:1438903164217:dw|

I took notes and can I tell you what I have and see if its all of them

you can apply the steps for any factoring

I wrote out everything above look again
and go all the way to the end

okay so it y^2(3x+4)(x-2)

yes and why |dw:1438905177813:dw|

do you understand the steps now?

yes

|dw:1438905441189:dw|

|dw:1438905837998:dw||dw:1438905995999:dw|

do you want to try this one
x^2 + 7x + 12

so to factor find a,b,c then find the common one and that's it

what is your a,b,c here

a is x^2 b is 7x and c is 12

a, b, c are just the numbers

we use a, b, c for the general equation

okay so bis 7 and c is 12 but im not sure what a is maybe 1

correct

a*c = 1* 12 = 12
next step factors of 12

1,12 2,6, 3,4

okay so the next step would be to regroup in two sets?

we rewrite before we can group

|dw:1438907098686:dw|

ooo then would you use FOIL

|dw:1438907153246:dw|

|dw:1438907213735:dw|

I goy an answer of 15x^2+55x but I don't think that's right

okay I see it now

think of FOIL and factor as opposites
FOIL to expand and factor to "put in parenthesis"

|dw:1438907593062:dw|

|dw:1438907801534:dw|

beauty of math no one approach for the same solution

okay I see it now thank you so much and once we group I=the final answer will be (x+6)(x-6)

yes

you are welcome all the best
