Calculation: (x-1) / (x ^ 2 + 3x + 2) + 6 / (2 + x-x ^ 2) - (10-x) / (4-x ^ 2) I'm sorry that one was wrong. This one is absolutely right

(x-1)/(x^2+3x-2)+6/(2+x-x^2)-(10-x)/(4-x^2)=(x-1)/[(x+1)(x+2)]-6/[(x+1)(x-2)]-(x-10)/[(x+2)(x-2)]=(x-1)(x-2)/[(x-2)(x+1)(x+2)]-6(x+2)/[(x+2)(x-1)(x-2)]-(x-10)/[(x-2)(x+2)]=(x^2-3x+2-6x-12)/[(x-1)(x+2)...
