x/x-2 - x+1/x = 8/x^2-2x

notice the last denominator factors to x(x-2) and those factors are found in the other two fractions
so x(x-2) is the lowest common denominator.

now multiply each term by that x(x-2) to get

(x)(x) -(x+1)(x-2) = 8

simplify and solve

I got x=6

    Problem 2: (x+2)/(2x^2+5x+2) - (x-3)/(2x^2-5x-3) What I did: 2x^2+5x+2 factors are (2x+1)(x+2) 2x^2-5x-3 factors are (2x+1)(x-3) Then: (x+2)/(2x+1)(x+2) - (x-3)/(2x+1)x-3) So the common denominator is (2x+1)(x+2)(x-3) using that
