    2x 2+3x - 4, 8-3x, - 5x 2 + 2

    Im guessing that 2x (2) ?

    (4x+3x-4) + (8-3x) + (-10x+2)

    7x-4+8-3x-10x+2

    Add all x's

    14x

    Add all the integers.

    6

    So, 14x + 6.

    What is the second line?

    -3x (2) - 2-7x (2) - 2-3x (2) + 6-7x (2) - 6x-2

    So ... - 6x-2-14x-2-6x-2-14x-6x-2

    -6 is the integer.

    -46x is the variables.

    -46x-6
