数学题a(a减1)(a减2)减6a(a减1)(a减2)减6怎么算?
a(a-1)(a-2)-6
根据 先算乘除后算加减的原则 进行计算,带括号的要先算
先算(a-1)(a-2)得 a^2-3a+2
再算a(a^2-3a+2)得a^3-3a^2+2a-6

a(a减1)(a减2)减6
=a(a-1)(a-2)-6
=a(a^2-3a+2)-6
=a^3-3a^2+2a-6

a(a减1)(a减2)减6
=a(a-1)(a-2)-6
=a(a^2-3a+2)-6
=a^3-3a^2+2a-6

a(a减1)(a减2)减6
=a(a-1)(a-2)-6
=a(a^2-3a+2)-6
=a^3-3a^2+2a-6
