Lim ((x-2)(x-3))/((x-3)(x-5))=lim(x-2)/(x-5)=(3-2)/(3-5)= - 1/2 = -0.5;                             419.    Lim ((x²+x-2)(x-1))/((x³+x²+x-3)(x-1))= lim (x²+x-2)/( x³+x²+x-3)= lim((x-1)(x+2))/((x-1)(x²+2x+3))=lim (x+2)/(x²+2x+3)=(1+2)/(1+2+3)=3/6=1/2=0.5;           420.   …=lim(x³+x²+x-1)/(x^4+x³+x²+x-3)=(1+1+1-1)/(1+1+1+1-3)=2   и так далее
