Question

What is the value of the coefficient of "a" when the quadratic equation y = (3x + 1)(3x − 2) is written in standard form?

−2

−3

9

6

Answer 1

Any ideas?

Answer 2

Nope

Answer 3

but i think its is B

Answer 4

why?

Answer 5

I think i am not sure

Answer 6

Use FOIL on $$\huge y = (3x + 1)(3x − 2) $$

Answer 7

wait be right back

Answer 8

well i think it is A

Answer 9

why?

Answer 10

idk

Answer 11

you should multiply

Answer 12

(3x + 1)(3x − 2) FOIL method

Answer 13

like the person above wrote..so start 3x(3x)+1(3x)+.. keep going and recall that the number in front of the \[x^2 \] is your a

Answer 14

so remember the way quadratics are written are in this standard form: y=\[ax^2+bx+c\]

Answer 15

goodluck, keep going! you are almost at your desire answer !

Answer 16

is it D

Answer 17

why?

Answer 18

If it is D, then why is it so?

Answer 22

OpenStudy values the Learning process - not the ‘Give you an answer’ process
- guide the asker to a solution.

Answer 23

Learning to "teach yourself" is a skill that no school teaches.

Answer 24

Come on you are almost there! Look here is an example of foil :
if you have for example y=(x-1)(2x-5) then when you foil, then you get this==>
(x)(2x)+(x)(-5)+(-1)(2x)+(-1)(-5) now you try with your problem! Goodluck,the best way to get the answer is to try it! You can post your work and we can help you see if you made any mistakes.

Answer 25

wait i will be right back

Answer 26

Yes we can wait to see your work.

And it was explained again above.

Answer 31

there not the same

Answer 32

What is not the same?

Answer 33

?? The problems?? Of course not. But the way you FOIL is.

Answer 34

what ?

Answer 35

Multiply the first terms of the binomials please $$\huge (3x + 1)(3x-2)$$

Answer 36

9x

Answer 37

almost.

Answer 38

\(3x\cdot 3x\) = ?

Answer 39

9

Answer 40

No, you were closer before.

Answer 41

yeah 9x
