    Answer:

    -9x^3 + 5x^2 + 6x-10

    Step-by-step explanation:

    Lorne subtracted 6x^3 - 2x + 3 from -3x^3 + 5x^2 + 4x - 7

    We need to subtract  6x^3 - 2x + 3

    -3x^3 + 5x^2 + 4x - 7 - (6x^3 - 2x + 3)

    Multiply negative sign inside the parenthesis

    -3x^3 + 5x^2 + 4x - 7 -6x^3 +2x - 3

    Now combine like terms to simplify it

    -3x^3-6x^3 + 5x^2 + 4x+2x - 7 - 3

    -9x^3 + 5x^2 + 6x-10

    6x^3-2x+3-(3x+5x^2+4x-7)          distribute the negative through the parenthesis

    6x^3-2x+3x-5x^2-4x+7                 combine like terms

    answer is 6x^3-5x^2-3x+10
