[ 1/1 Equation]
    Work: Find the solution of equation （a+25/4）（a+25/4）+187/16 = 1+（a+4）（a+4） .
    Question type: Equation
    Solution:Original question:
     ( a + 25 ÷ 4)( a + 25 ÷ 4) + 187 ÷ 16 = 1 + ( a + 4)( a + 4)
     Left side of the equation = ( a + 25 ÷ 4)( a + 25 ÷ 4) +
187
16
    The equation is transformed into :
     ( a + 25 ÷ 4)( a + 25 ÷ 4) +
187
16
 = 1 + ( a + 4)( a + 4)
    Remove the bracket on the left of the equation:
     Left side of the equation = a ( a + 25 ÷ 4) + 25 ÷ 4 × ( a + 25 ÷ 4) +
187

 = 1 + ( a + 4)( a + 4)
    Remove the bracket on the right of the equation:
     Right side of the equation = 1 + a ( a + 4) + 4( a + 4)
                                               = 1 + a a + a × 4 + 4( a + 4)
                                               = 1 + a a + 4 a + 4 a + 4 × 4
                                               = 1 + a a + 4 a + 4 a + 16
                                               = 17 + a a + 8 a
    The equation is transformed into :
      a a +
