    Question type: Equation
    Solution:Original question:

a

(

46

−

a

)

×

480

=

0

    Remove the bracket on the left of the equation:

Left side of the equation =

a

−

a

a

×

480

=

0

    After the equation is converted into a general formula, it is converted into:
    ( a +0 )( a - 46 )=0
    From
        a + 0 = 0
        a - 46 = 0
    it is concluded that:：
        a₁=0
        a₂=46    
    There are 2 solution(s).
