1已知X×X-X-1=0,求-X×X×X-2×X×X+2010的值
2已知m×m+n×n-6m+10n+34=0,则m+n的值是多少
3Herry 今天和父母去动物园,他们看了许多动物,Herry最喜欢的是大象.假如你是Herry,请用下面的词描述一下今天的经历
zoo,see,best,smart,friendly,eat,other,happy

1、因为X²-X-1=0,所以X³-2X²+2010=X³-X²-X-（X²-X-1）+2009=2009；
2、m²+n²-6m+10n+34=0可以配成完全平方形式为（m-3)²+（n+5)²=0,所以m=3,n=-5,m+n=-2;
3、Today ,Herry went to the zoo with her partents.They saw many animals.Of all these animals ,Herry liked the elephant best .Because she thought that elephants were smart and friendly.At noon,they ate some food and then visited other animals .Today they felt very happy .
