[ 1/1 Equation]
    Work: Find the solution of equation 2*x4-7*x2-15 = 0 .
    Question type: Equation
    Solution:Original question:
     2 x × 47 x × 215 = 0
     Left side of the equation = 8 x 14 x 15
                                             = - 6 x 15
    The equation is transformed into :
      - 6 x 15 = 0

    Transposition :
      - 6 x = 0 + 15

    Combine the items on the right of the equation:
      - 6 x = 15

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 15 = 6 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 :
     6 x = - 15

    The coefficient of the unknown number is reduced to 1 :
      x = - 15 ÷ 6
        = - 15 ×
1
6
        = - 5 ×
1
2

    We obtained :
      x = -

2
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 2.5
