计算下列各式的值.(多项式除以多项式)
(1) (3x³+10x²+13x-27)÷(x²+2x-3) (2) (2x²+x³-2)÷(x²-1) (3) A=9xˆ4-21x³-2x²+11x-2,B=3x³-5x²-4x+1,求:A²/B².

计算下列各式的值.(多项式除以多项式)(1) (3x³+10x²+13x-27)÷(x²+2x-3) (2) (2x²+x³-2)÷(x²-1) (3) A=9xˆ4-21x³-2x²+11x-2,B=3x³-5x²-4x+1,求:A²/B².
答:
多项式的除法类似小学阶段的竖式除法,见下图所示的过程:
(3x³+10x²+13x-27)÷(x²+2x-3) =3x+4 余14x-15

其余两道题目类似求解即可
