The given equation is:

+x++-+1%2F2 2x%5E3+-+4x%5E2+%2B+3x+-+2%2F5

x+-+1%2F2 %2810x%5E3+-+20x%5E2+%2B+3x+-+2%29%2F5

%282x+-+1%29%2F2 %2810x%5E3+-+20x%5E2+%2B+3x+-+2%29%2F5

%28%282x+-+1%29%2810x%5E3+-+20x%5E2+%2B+3x+-+2%29%29%2F10

%2820x%5E4+-+10x%5E3+-+40x%5E3+%2B+20x%5E2+%2B+6x%5E2+-+3x+-+4x+%2B+2%29%2F10

%2820x%5E4+-+50x%5E3+%2B+26x%5E2+-+7x+%2B+2%29%2F10

Hence, the solution.
