[ 1/1 Equation]
    Work: Find the solution of equation (360-x)[2(480-x)+160] = 0 .
    Question type: Equation
    Solution:Original question:
     (360 x )(2(480 x ) + 160) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 360(2(480 x ) + 160) x (2(480 x ) + 160)
                                             = 360 × 2(480 x ) + 360 × 160 x (2(480 x ) + 160)
                                             = 720(480 x ) + 57600 x (2(480 x ) + 160)
                                             = 720 × 480720 x + 57600 x (2(480 x ) + 160)
                                             = 345600720 x + 57600 x (2(480 x ) + 160)
                                             = 403200720 x x (2(480 x ) + 160)
                                             = 403200720 x x × 2(480 x ) x × 160
                                             = 403200880 x x × 2(480 x )
                                             = 403200880 x x × 2 × 480 + x × 2 x
                                             = 403200880 x x × 960 + x × 2 x
                                             = 4032001840 x + x × 2 x
    The equation is transformed into :
     4032001840 x + x × 2 x = 0

    
        x=360
    
    There are 1 solution(s).
