化简式子,(x + 1) × (x - 2) × (x - 3)(x + 1) × (x - 2) × (x - 3)求化简

化简式子,(x + 1) × (x - 2) × (x - 3)(x + 1) × (x - 2) × (x - 3)求化简
化简式子,(x + 1) × (x - 2) × (x - 3)
(x + 1) × (x - 2) × (x - 3)求化简

化简式子,(x + 1) × (x - 2) × (x - 3)(x + 1) × (x - 2) × (x - 3)求化简
原式=(x^2 -x-2)(x-3)
=x^2 (x-3)-x(x-3)-2(x-3)
=x^3 -3x^2 -x^2 +3x-2x+6
=x^3 -4x^2 +x+6

原式=(x^2-x-2)(x-3)=x^3-3x^2-x^2+3x-2x+6=x^3-4x^2+x+6
