Add the following polynimal
(1/10x^2-1/2x-3/10)+(1/2x^2+1/4x-1/5
Show me how to do this please?

  • algebra -

    (1/10x^2-1/2x-3/10)+(1/2x^2+1/4x-1/5

    remember , we can only add "like" terms

    = (1/10)x^2+(1/2)x^2 + (-1/2)x+(1/4)x -3/10-1/5
    = (3/5)x^2 - (1/4)x - 1/2

    ( I added the fraction of the like terms)
