[ 1/1 Equation]
    Work: Find the solution of equation x2-12x-4 = 0 .
    Question type: Equation
    Solution:Original question:
      x × 212 x 4 = 0
     Left side of the equation = - 10 x 4
    The equation is transformed into :
      - 10 x 4 = 0

    Transposition :
      - 10 x = 0 + 4

    Combine the items on the right of the equation:
      - 10 x = 4

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 4 = 10 x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     10 x = - 4

    The coefficient of the unknown number is reduced to 1 :
      x = - 4 ÷ 10
        = - 4 ×
1
10
        = - 2 ×

5

    We obtained :
      x = -

5
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 0.4
