[ 1/1 Equation]
    Work: Find the solution of equation p×p+2p×7÷10 = 32÷100 .
    Question type: Equation
    Solution:Original question:
      p p + 2 p × 7 ÷ 10 = 32 ÷ 100
     Left side of the equation = p p +
7
5
p
    The equation is transformed into :
      p p +
7
5
p = 32 ÷ 100
     Right side of the equation =
8
25
    The equation is transformed into :
      p p +
7
5
p =
8
25

    After the equation is converted into a general formula, it is converted into:
    ( 5p + 8 )( 5p - 1 )=0
    From
        5p + 8 = 0
        5p - 1 = 0

    it is concluded that::
        p1=-
8
5
        p2=
1
5
    
    There are 2 solution(s).
