Question

Using complete sentences, explain how to completely factor 3x2 − 3x − 60

Answer 1

first you would factor out a 3 which gives you?

Answer 2

Which 3 would I factor out?

Answer 3

all of them. factor a 3 out of all of it.

Answer 4

3x2-60????

Answer 5

it would be 3(x^2-x-20)

Answer 6

That's the answer? Please explain how to get there.

Answer 7

Sorry, but I forgot to say the 3x2 is actually 3x to the 2nd power

Answer 8

no thats just step one... all you do is you look at the problem, "3x^2-3x-60" looking at that there is a leading coefficient of 3 (3x^2) so you want to get the x^2 by itself, to do that you divide it all by 3 which gives you the 3(x^2-x-20)

Answer 9

So can you post all the steps, one after the other?

Answer 10

yeah but does that make sense

Answer 11

Okay, if you can... Can you check this answer???
Select the factors of x2 − 14x + 49

(x + 49)(x + 1)

(x + 7)(x + 7)

(x − 7)(x − 7)

(x − 49)(x − 1) (My Answer)

Answer 12

when factoring your terms a and b in (x+-a)(x+-b) should do the following
a*b=49 but when you add them together(a+b) it should equal 14

Answer 13

So the answer is B?

Answer 14

well, in your question it is -14 so thats my bad. so it would be

Answer 15

So the answer would be C then?

Answer 16

yupp!

Answer 17

Yep, the correct answer was C... Thanks so much! You helped me a lot.

Answer 18
