您好： 1x²-2x-（2x+1）
=x²-1=（x+1）（x-1） 29.9²+9.9X0.2+0.01=9.9²+2x9.9X0.1+0.01=(9.9+0.1)²=100 3;-;=（）（）=4025 如果本题有什么不明白可以追问,如果满意记得采纳如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,谢谢.祝学习进步!
1.x² - (2x+1)= x² - 2x - 1= (x-1)² - 2= (x-1 + √2) * (x-1 - √2)2.9.9²+9.9X0.2+0.01= (9.9 + 0.1)²= 10²= 100;-;= ()()= 40251/2(8-x)(6-x)=1/2*1/2*8*6 (8-x)(6-x)=24 48-14x+x²=24 x²-14x+24=0 (x-2)(x-12)=0 x=2.x=12?为什么是减14,而不是减2呢?_作业帮
