1.2345*0.2345*2.469-1.2345³-1.2345*0.234² 等于-1.2345,咋算的?
1.2345*0.2345*2.469-1.2345³-1.2345*0.234²
=-1.2345*（1.234² -2*0.2345*1.2345-1.2345²）
=-1.2345*(1.234-0.234)²
=-1.2345
1.2345*0.2345*2.469-1.2345³-1.2345*0.234²
=-1.2345*（1.234² -2*0.2345*1.2345-1.2345²）
=-1.2345*(1.234-0.234)²
=-1.2345
1.2345*0.2345*2.469-1.2345³-1.2345*0.234²
=-1.2345*（1.234² -2*0.2345*1.2345-1.2345²）
=-1.2345*(1.234-0.234)²
=-1.2345
