①a^2-b^2/a-b=(a+b)(a-b)/(a-b)=a+b
②x+y/x^2+xy=(x+y)/x(x+y)=1/x
③m^2-16/3m-12=(m+4)(m-4)/3(m-4)=(m+4)/3
④a^2-6a+9/a^2-9=(a-3)²/(a+3)(a-3)=(a-3)/(a+3)
⑤4b^2-a^2
⑥-4x^2y 这两个少分母
⑦2(x-y)^2/6(y-x)^3=2(y-x)²/6(y-x)³=1/3(y-x)
⑧a^2-4a+4/a^2-4=(a-2)²/(a+2)(a-2)=(a-2)/(a+2)
⑨x^2-2xy+y^2/ax-ay=(x-y)²/a(x-y)=(x-y)/a
⑩2a^2+2ab/3ab+3b^2=2a(a+b)/3b(a+b)=2a/3b
