want to know if this right simplify and show all work

  • algebra - ,

    in the second line of your solution, 2*(-3x^2) = -6x^2 not 6y^2. thus,
    -3x^2 + 4xy + 7y^2 - 6x^2 + 10xy + 22y^2
    -9x^2 + 14xy + 29y^2

    ..for the second problem, i think there are typos. please check the problem again. also, 100^2 is not equal to 200.
