[1/1 Formula]
    Work: Calculate the value of equation 19*(250-404)^2+30*(350-404)^2+42*(450-404)^2+18*(550-404)^2 .
    Question type: Mathematical calculation
    Solution:
          19*(250-404)^2+30*(350-404)^2+42*(450-404)^2+18*(550-404)^2
        =19*(-154)^2+30*(350-404)^2+42*(450-404)^2+18*(550-404)^2
        =19*(-154)^2+30*(-54)^2+42*(450-404)^2+18*(550-404)^2
        =19*(-154)^2+30*(-54)^2+42*46^2+18*(550-404)^2
        =19*(-154)^2+30*(-54)^2+42*46^2+18*146^2
        =19*23716+30*(-54)^2+42*46^2+18*146^2
        =19*23716+30*2916+42*46^2+18*146^2
        =19*23716+30*2916+42*2116+18*146^2
        =19*23716+30*2916+42*2116+18*21316
        =450604+30*2916+42*2116+18*21316
        =450604+87480+42*2116+18*21316
        =450604+87480+88872+18*21316
        =450604+87480+88872+383688
        =538084+88872+383688
        =626956+383688
        =1010644

    Answer:19*(250-404)^2+30*(350-404)^2+42*(450-404)^2+18*(550-404)^2=1010644
