[ 1/1 Equation]
Work: Find the solution of equation n（n+1） = 0 .
Question type: Equation
Solution:Original question:
| n | ( | n | + | 1 | ) | = | 0 |
| Left side of the equation = | n | n | + | n | × | 1 |
| n | n | + | 1 | n | = | 0 |
After the equation is converted into a general formula, it is converted into:
( n + 1 )( n +0 )=0
From
n + 1 = 0
n + 0 = 0
it is concluded that:：
n1=-1
n2=0
There are 2 solution(s).
