           ☆3 equations

[ 1/3 Equation]
    Work: Find the solution of equation a*a = 8 .
    Question type: Equation
    Solution:Original question:

a

a

=

8

    After the equation is converted into a general formula, it is converted into:
    ( a + √8 )( a - √8 )=0
    From
        a + √8 = 0
        a - √8 = 0
    it is concluded that:：
        a₁=-√8
        a₂=√8    
    There are 2 solution(s).

[ 3/3 Equation]
    Work: Find the solution of equation b*b = 0 .
    Question type: Equation
    Solution:Original question:

b

b

=

0

    After the equation is converted into a general formula, it is converted into:
    ( b - 0 )( b - 0 )=0
    From
        b - 0 = 0
        b - 0 = 0
    it is concluded that:：
        b₁=0
