Question

Factor the following trinomial.
w18 – 9w9y5 + 14y10

anonymous · Answer

Take whatever the things you can take as common..

anonymous · Answer

Hint: What squared equals w^18?

anonymous · Answer

No, here you can do one thing more:

put$$w^9 = x$$

So, the equation becomes:

$$x^2 - (9y^5)x + 14y^{10} = x^2 - (7y^5)x - (2y^5)x + 14y^{10}$$

$$x(x-7y^5) - 2y^5(x - 7y^5) = (x - 2y^5)(x-7y^5)$$

Now you know what is substituted as x??

replace x by that value and get the answer...
