Answer:
tanx·secx
Step-by-step explanation:
To simply this, you can begin by factoring sin x out of the numerator to become:
Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:

First of all, we can convert
to tanx. However, we have a remaining
which, using reciprocal identities, will become sec x.
Finally, we get our answer as tanx·secx.
Answer:
x^3-4x^2-5x+18
Step-by-step explanation:
When you distribute (x-2) (x^2-2x-9) you get x^3-2x^2-2x^2+4x-9x+18 combine like terms and you get your answer
