Question

x（x-1）=132 怎么解 过程

Answer 1

x（x-1）=132
得出x^2-x-132=0
归因得出（x-12）*（x+11）=0
得出x1=12、x2=-11

Answer 2

展开得x^2-x-132=0
分解因式得(x+11)(x-12)=0
解得x=12或-11

Answer 3

x方-x-132=0
(x-12)(x+11)=0
x=12或-11

Answer 4

x(x-1)=132
x^2-x-132=0
(x-12)(x+11)=0
x=12或x=-11

Answer 5

解:x^2-x-132=0
(x-12)(x+11)=0
x-12=0或x+11=0
x1=12,x2=-11
