[ 1/1 Equation]
    Work: Find the solution of equation 5(p+3)×(-p-5+3/p) = 1.2 .
    Question type: Equation
    Solution:Original question:
     5( p + 3)( - p 5 + 3 ÷ p ) =
6
5
    Remove a bracket on the left of the equation::
     5 p ( - p 5 + 3 ÷ p ) + 5 × 3( - p 5 + 3 ÷ p ) =
6
5
    The equation is reduced to :
     5 p ( - p 5 + 3 ÷ p ) + 15( - p 5 + 3 ÷ p ) =
6
5
    Remove a bracket on the left of the equation:
      - 5 p p 5 p × 5 + 5 p × 3 ÷ p + 15( - p 5 + 3 ÷ p ) =
6
5
    The equation is reduced to :
      - 5 p p 25 p + 15 p ÷ p + 15( - p 5 + 3 ÷ p ) =
6
5
    Remove a bracket on the left of the equation:
      - 5 p p 25 p + 15 × 1 ÷ 115 p 15 × 5 =
6
5
    The equation is reduced to :
      - 5 p p 25 p + 1515 p 75 + 45 ÷ p =
6
5
    The equation is reduced to :
      - 5 p p 40 p 60 + 45 ÷ p =
6
5
     Multiply both sides of the equation by: p
      - 5 p p p 40 p p 60 p + 45 =
6
5
p

    The solution of the equation:
        p1≈-5.452356 , keep 6 decimal places
        p2≈-3.083044 , keep 6 decimal places
        p3≈0.535400 , keep 6 decimal places
    
    There are 3 solution(s).
