Sup, I don't know how to do this. I must operate and then simplify. I have already done more than half of these exercises, but I am having problems with these.

Could someone do it for me please?

some of them are very easy e.g. 17:

eliminate 4 and x^2 and you obtain

3x/(x-1)

I'll do another one:

15) Write the factor on the left as a fraction by determining a common denominator:

(x+1)(x-1) = x^2 - 1

so the term on the left is

(x-1)/(x^2 - 1) + 2(x+1)/(x^2-1) = (3x+1)/(x^2-1)

You can now eliminate x^2-1 (for x different than +/-1) and obtain for the whole term

(3x+1)/(x^2+2x+1) = (3x+1)/(x+1)^2

Well, it's easier than I thought.

I was basically trying Ruffini on everything haha.

Thanks m8.

What the fuck? These are like less than high school level. Are you sure you're 18 y/o?

19. I repeated two years, I'm in Spain and these are the easy maths, because I am studying history, not science.
