kittybasil:

background-transparent-animated-5.gif

jhonyy9:

Nicole are you here ?

kittybasil:

by FOIL:\[(4x-7)(2x+3)\]\[(4x\cdot2x)+(4x\cdot3)+(-7\cdot2x)+(-7\cdot3)\]

jhonyy9:

4x×2x exactly @kittybasil

kittybasil:

multiply that out and rearrange in order by term degree what did you get? I'm in the middle of Organic Chemistry so I can't go in-depth

Nicole:

What so what do I do now?

jhonyy9:

jhonyy9:

you dont wan collaborate ?

Nicole:

8x^2

jhonyy9:

ok continue please

jhonyy9:

4x*3 = ?

Nicole:

is 12x

Nicole:

-7*2x = -14x

Nicole:

-7*3= -21

Nicole:

what do I do now

jhonyy9:

assume the same terms

jhonyy9:

8x^2 do you have same term again ?

jhonyy9:

no so the first term of this quadratis will be 8x^2 and now the x terms ,so from this there are two terms

Nicole:

im thinking A?

jhonyy9:

please take the necessary way

jhonyy9:

12x-14x = ?

jhonyy9:

A not is right

Nicole:

-2x

Nicole:

?

jhonyy9:

yes so you know 8x^2 -2x ... and the last one term ?

jhonyy9:

-7*3 = ?

Nicole:

-21

Nicole:
