Best ResponseYou've already chosen the best response.0Then we need to look at each answer to see if these contain the desired factors. Start with A and see what you can factor out. Is it what we are looking for? If yes, then this is your answer, if no go to the net one and do it again.

Best ResponseYou've already chosen the best response.0Perhaps this isn't factoring out something, but what are the factors of the problem. When you FOIL the factors you would get the problem you now see.

Best ResponseYou've already chosen the best response.0Good Job, so the first part of what you should be writing down is (2 )(6 )

Best ResponseYou've already chosen the best response.0Since you have an x^2 next to the 12 what do we need to multiply that gives us x^2?

Best ResponseYou've already chosen the best response.0yes, so if a * a = a^2 what letters do we need to get x^2?

Best ResponseYou've already chosen the best response.0Yes, so now show me where the x's go in what you are writing down

Best ResponseYou've already chosen the best response.0ok but leave some space because we need to put more of the problem inside (2x )(6x ) 12x^2 – 2x – 20 so we have the 12x^2 now what factors make up 20?

Best ResponseYou've already chosen the best response.0ok. but let's take a look at what question we are being asked. Do any of the factors have 3x + 4 as a factor?

Best ResponseYou've already chosen the best response.0so let's look at 12x^2 again. instead of 2*6 is there anything else when multiplied that equals 12?

anonymous

Best ResponseYou've already chosen the best response.0yes, 1 and 12 do = 12 but are they the factors we are looking for? are there any factors that we are looking for that =12?

Best ResponseYou've already chosen the best response.0Good job. so show me how you write that down with our x's

Best ResponseYou've already chosen the best response.0Well, we had (2x )(6x ) before, but we found out 2*6 are not part of our factors. Now, using our factors replace 2 and 6 with 3 and 4

Best ResponseYou've already chosen the best response.0ok. Now we are still working on our 20. and 2 and 10 are not part of our factor that we are looking for. 3x + 4 which numbers contain one of our factors when multiplied give us 20?

anonymous

Best ResponseYou've already chosen the best response.0Do you see that we have part of the correct answer (3x )(4x ) 3x + 4 Now we need to use the 4 to get 20. What could we multiply 4 by to give us 20?

Best ResponseYou've already chosen the best response.0ok. So lets put them in (3x+4)(4x5) now FOIL it out and tell me if it is = 12x^2 – 2x – 20

Best ResponseYou've already chosen the best response.0I mutiplied 3 and 4 and got 12x. Then I multiplied 4 and 5 and got 20
