Question

Factor the following trinomial.

w18 – 9w9y5 + 14y10

Answer 1

Ummm where's the exponenets

Answer 2

18, 9,5,10

Answer 3

\[w ^{18}-9w ^{9}y ^{5}+14y ^{10}\] Does it look like this?

Answer 4

yes

Answer 5

@Calcmathlete I think you'd be better at this than me :)

Answer 6

Find factors of 14 that add up to -9.

Answer 7

idk that's why i'm asking for help

Answer 8

so it would be -2 and -7

Answer 9

Ok. Even though it looks a lot different, it is still a factorable trinomial.
\[w ^{18}-9w ^{9}y ^{5}+14y ^{10} \implies (w^9 - 2y^5)(w^9 - 7y^5)\]

Answer 10

Remember. THese are exponents. \[w^9 \times w^9 = w^{9 + 9} = w^{18}\]

Answer 11

so would that be the answer?

Answer 12

\[w ^{18}-9w ^{9}y ^{5}+14y ^{10} \implies (w^9 - 2y^5)(w^9 - 7y^5)\]
The one on the right is the answer.

Answer 13

thank you so much you guys!

Answer 14

np :)
