@haleyelizabeth2017 this one

OpenStudy (haleyelizabeth2017):

is that \(9x^2\)?

OpenStudy (liv1234):

Yeah.

OpenStudy (haleyelizabeth2017):

-4

OpenStudy (haleyelizabeth2017):

lol

OpenStudy (haleyelizabeth2017):

Okay, so let's see...

OpenStudy (liv1234):

I know what the answer is (3x-2)(3x+2), but I need the steps aha

OpenStudy (haleyelizabeth2017):

Okay

OpenStudy (haleyelizabeth2017):

Well, there aren't really any steps...

OpenStudy (haleyelizabeth2017):

You can put the answer and then checking your work?

OpenStudy (haleyelizabeth2017):

Think that would work?

OpenStudy (haleyelizabeth2017):

Well, explain that 3x times 3x is 9x^2, and 2*-2 is -4...

OpenStudy (liv1234):

Ohh okay, that makes sense haha

OpenStudy (haleyelizabeth2017):

and that 18x-18x is 0, so we leave that out. Which leaves us with (3x-2)(3x+2)

OpenStudy (haleyelizabeth2017):

Then just check your work.

OpenStudy (liv1234):

Ohh alright, when I finish typing that, can you help me with a few more?

OpenStudy (haleyelizabeth2017):

Okay, yes!

OpenStudy (liv1234):

OpenStudy (haleyelizabeth2017):

let's see...we know we're gonna need the last digits to be +2 and +3, right? because they multiply to 6

OpenStudy (liv1234):

I got it!(:

OpenStudy (haleyelizabeth2017):

Oh lol it's (x+2)(4x+3) lol did you need help explaining it, or do you got it?

OpenStudy (liv1234):

I need help explaining it

OpenStudy (haleyelizabeth2017):

Okay, so we can just do what we did last time.

OpenStudy (liv1234):

Can you write it out for me?

OpenStudy (haleyelizabeth2017):

Just check your answer. Hopefully it's good enough lol sure!

OpenStudy (haleyelizabeth2017):

Step 1:\[(x+2)(4x+3)\] 2:\[4x^2+3x+8x+6\] 3:\[4x^2+11x+6\]
