How do you determine if the two expressions are equivalent using the subtraction method?$$\frac{2x^3+7x^2-5x-6}{x+1} - [(2x^2+5x-10) + \frac{4}{x+1}] $$
The textbook says that they're equivalent. I know that, using the subtraction method, they have to equal 0 in order to be equivalent. But, I'm not getting that. This is what I've done so far:
$$2x^2+7x-5-\frac{6}{x+1} - [(2x^2+5x-10) + \frac{4}{x+1}] $$
Then I'm not sure what to do...
