Answer 3

pictured added you can look on it

Answer 4

well thats an odd way to program something ...

Answer 5

as is, this is just a quadratic equation disguised

Answer 6

let y^2 = x

3x^2 - 2x - 5

Answer 7

my method is:

mutliply the first and last coefficients; and then find factors of that that add to the middle term

Answer 8

thats factor i tryed wolframalpha but answers don't match

Answer 9

3x^2 - 2x -5
^ ^
3(-5) = -15

since its already obvious that -5+3 = -2 the second step is just redundant for this

setup the factors such that we divide out the first coeff from these results

(x-5/3) (x+3/3) simplify them

(x-5/3) (x+1) and if theres a fraction left, put its bottom out front
^^

(3x-5) (x+1)

since y^2 = x, sub it back in

(3y^2 - 5) (y^2 + 1)

Answer 10

also you can see grid on picture i added

Answer 11

i can, but its up to you to work that into what they expect from you

Answer 12

on grid they putted 4 allready

Answer 13

thats a 5 yes

Answer 14

so all answers come up they don't match

Answer 15

5*

Answer 16

( 3 y \(^2\) - 5 ) ( y \(^2\) + 1 )
^

Answer 17

you have all the parts available to you ... put them in their correct places

Answer 18

it can't be y because in choices only a , b ,c or letter don't matter?

Answer 19

your picture ands in "x y z"

Answer 20

lol sorry i was looking on diffrent problem

Answer 21

click on "(", drag it to the 1st square and drop it in
click on "3", drag it to the 2nd square and drop it in
click on "y", drag it to the 3rd square and drop it in
click on "\(^2\) ", drag it to the 4th square and drop it in
click on "-", drag it to the 5th square and drop it in
etc ....

:)

Answer 22

Factor completely, then place the factors in the proper location on the grid.

9 - 6a - 24a^2 i also stuck on this one
