Question

9tx^2-15tx-6t factorize

Answer 1

Yeah, I just corrected my mistake if you look at the other question again.

Answer 2

3t(3x^2-5x-2)
3t(3x^2-6x+1x-2)
3t(3x(x-2)+1(x-2))
3t(x-2)(3x+1)

Answer 3

so this is correct.

Answer 4

It is now....

Answer 5

thanks

Answer 6

How did you know it wasn't correct the first time?

Answer 7

I came back and realized my mistake....what did you do?

Answer 8

coefficient 3 was missing which complicated the answer.

Answer 9

I see

Answer 10

I corrected another one as well where I didn't completely simplify...

Answer 11

which one is that?

Answer 12

You can find it. It has an answer, then a simplified form after it.

Answer 13

9m^2-30m+21

Answer 14

3(3m^2-10m+7)
3(3m^2-3m-7m+7)

3(3m(m-1)-7(m-1))
3(m-1)(3m-7)

Answer 15

thank you

Answer 16

2mn^2-19mn-21m factorize.

Answer 17

How many of these do you have?

Answer 18

my answer is m(2n-21) (n+1)

Answer 19

10 of them

Answer 20

but they already been answered. I'm just caution about the answers.
