化简(X+2)\(X^2+X)+(2X+1)\(X^2+3X+2)-(X-3)\(X^2+2X)

化简(X+2)\(X^2+X)+(2X+1)\(X^2+3X+2)-(X-3)\(X^2+2X)
化简(X+2)\(X^2+X)+(2X+1)\(X^2+3X+2)-(X-3)\(X^2+2X)

化简(X+2)\(X^2+X)+(2X+1)\(X^2+3X+2)-(X-3)\(X^2+2X)
原式=(x+2)/x(x+1)+(2x+1)/(x+1)(x+2)-(x-3)/x(x+2)
=[(x+2)^2+x(2x+1)-(x+1)(x-3)]/x(x+1)(x+2)
=(x^2+4x+4+2x^2+x-x^2+2x+3)/x(x+1)(x+2)
=(2x^2+7x+7)/(x^3+3x^2+2x)

(X+2)/(X^2+X)+(2X+1)/(X^2+3X+2)-(X-3)/(X^2+2X)
=(X+2)/X(X+1)+(2X+1)/(X+1)(X+2)-(X-3)/X(X+2)
=[(X+2)^2+X(2X+1)-(X+1)(X-3)]/X(X+1)(X+2)
=(X^2+4X+4+2X^2+X-X^2+2X-3)/X(X+1)(X+2)
=(2X^2+7X+1)/X(X+1)(X+2)
