Answer 1

Hi chadandticia_2009 :)

How are you dear?

Answer 2

fine u

Answer 3

your question look like this?

\[\Large w^{18}-9w^9y^5+14y^{10}\]

Answer 4

yes

Answer 5

can you help me?

Answer 6

someone please help?

Answer 7

I am also fine dear.

Answer 8

Do you know this formula,

\[\Large (\text{a-b})^2=\text{a}^2-2ab+\text{b}^2\]

Answer 9

yes how do I do it?

Answer 10

someone please help??????

Answer 11

So I know how I can help, is this multiple choice or a fill in answer?

Answer 12

fill in the answer.

Answer 13

Alright. First, find factors of 14 that add up to -9.

Answer 14

-23+14=-9

Answer 15

Um, -23 and 14 don't multiply to form 14.
Here are all the possible factors. Pair them up so that they add up to -9.
-1, -2, -7, -14, 1, 2, 7, 14

Answer 16

-2+ -7

Answer 17

Ok. Then, you have to remember how factoring works.
\[(w^{9} + factor1(y^{5}))(w^{9} + factor2(y^{5}))\]Can you finish it?

Answer 18

no still confused

Answer 19

(w^9+ -2y^5)(w^9+ -7y^5)

Answer 20

Pretty much.
\[(w^{9} - 2y^{5})(w^{9} - 7y^{5})\]

Answer 21

is that the final answer?
