    Work: Find the solution of equation 24*445(1+a)+24*545(1+a)(1+2a) = 21600(1+20a/9) .
    Question type: Equation
    Solution:Original question:
     24 × 445(1 + a ) + 24 × 545(1 + a )(1 + 2 a ) = 21600(1 + 20 a ÷ 9)
     Left side of the equation = 10680(1 + a ) + 13080(1 + a )(1 + 2 a )
    The equation is transformed into :
     10680(1 + a ) + 13080(1 + a )(1 + 2 a ) = 21600(1 + 20 a ÷ 9)
    Remove the bracket on the left of the equation:
     Left side of the equation = 10680 × 1 + 10680 a + 13080(1 + a )(1 + 2 a )
                                             = 10680 + 10680 a + 13080(1 + a )(1 + 2 a )
                                             = 10680 + 10680 a + 13080 × 1(1 + 2 a ) + 13080 a (1 + 2 a )
                                             = 10680 + 10680 a + 13080(1 + 2 a ) + 13080 a (1 + 2 a )
                                             = 10680 + 10680 a + 13080 × 1 + 13080 × 2 a + 13080 a (1 + 2 a )
                                             = 10680 + 10680 a + 13080 + 26160 a + 13080 a (1 + 2 a )
                                             = 23760 + 36840 a + 13080 a (1 + 2 a )
                                             = 23760 + 36840 a + 13080 a × 1 + 13080 a × 2 a
                                             = 23760 + 36840 a + 13080 a + 26160 a a
                                             = 23760 + 49920 a + 26160 a a
    The equation is transformed into :
     23760 + 49920 a + 26160 a a = 21600(1 + 20 a ÷ 9)
    Remove the bracket on the right of the equation:
     Right side of the equation = 21600 × 1 + 21600 × 20 a ÷ 9
                                               = 21600 + 48000 a
    The equation is transformed into :
     23760 + 49920 a + 26160 a a = 21600 + 48000 a
    This equation has no real solution!
