r(x)=3x+5/x^1+1, s(x)=x^2+3/3x-1
write the expression (2r-3x)(x) as a simplified ratio with the numerator and denominator each written as a sum of terms of the form cx^m and c0, for the term in the highest power in the numerator
(2r-3s)(x)=f(x)/g(x) where f(x)=? and g(x)=?

Question

r(x)=3x+5/x^1+1, s(x)=x^2+3/3x-1
write the expression (2r-3x)(x) as a simplified ratio with the numerator and denominator each written as a sum of terms of the form cx^m and c>0, for the term in the highest power in the numerator
(2r-3s)(x)=f(x)/g(x) where f(x)=?  and g(x)=?

$$\left( -3x^3+15x^2+15x-19 \right)\div \left( (x+1)(3x-1) \right)$$

Hope its right.

anonymous · Answer

hate to say it but i need f(x) and g(x) haha

anonymous · Answer

f(x) is the numerator function, and g(x) is the denominator. Just multiply out the two bottom factors and it'll give u the complete g(x)

??

im not that good yet

anonymous · Answer

well if this is your homework, you should know how to multiply (x+1)(3x-1). Can you do that?

anonymous · Answer

my bad, yes haha
