[ 1/1 Equation]
    Work: Find the solution of equation (22+2x)(29+2x)-29×22 = 29×22÷4 .
    Question type: Equation
    Solution:Original question:
     (22 + 2 x )(29 + 2 x )29 × 22 = 29 × 22 ÷ 4
     Left side of the equation = (22 + 2 x )(29 + 2 x )638
    The equation is transformed into :
     (22 + 2 x )(29 + 2 x )638 = 29 × 22 ÷ 4
    Remove the bracket on the left of the equation:
     Left side of the equation = 22(29 + 2 x ) + 2 x (29 + 2 x )638
                                             = 22 × 29 + 22 × 2 x + 2 x (29 + 2 x )638
                                             = 638 + 44 x + 2 x (29 + 2 x )638
                                             = 0 + 44 x + 2 x (29 + 2 x )
                                             = 0 + 44 x + 2 x × 29 + 2 x × 2 x
                                             = 0 + 44 x + 58 x + 4 x x
                                             = 0 + 102 x + 4 x x
    The equation is transformed into :
     0 + 102 x + 4 x x = 29 × 22 ÷ 4
     Right side of the equation =
319
2
    The equation is transformed into :
     0 + 102 x + 4 x x =
319
2

    The solution of the equation:
        x1≈-26.978053 , keep 6 decimal places
        x2≈1.478053 , keep 6 decimal places
    
    There are 2 solution(s).
