    (3x - 5) - (4x+6) When there is negative sign out side the bracket the sign changes 3x-5 -4x-6 can you do it now?

    you can rearrange the terms of 3x-5 -4x-6 to get 3x-5 -4x-6 3x-4x-5 -6 Now combine 3x and -4x to get what?

    (3x^2 - 2) + (2x^2 - 6x + 3) 3x^2 - 2 + 2x^2 - 6x + 3 ... parenthesis are unneeded here (3x^2+2x^2)+(-6x)+(-2+3) ... group like terms 5x^2 - 6x + 1 ... combine like terms So (3x^2 - 2) + (2x^2 - 6x + 3) simplifies to 5x^2 - 6x + 1

    total distance = result of adding up all the distances total distance = distance1 + distance2 + distance3 total distance = (3x-2)+(x^2-5)+(2x+7) total distance = 3x-2+x^2-5+2x+7 total distance = (x^2)+(3x+2x)+(-2-5+7) total distance = x^2+5x+0 total distance = x^2+5x So the simplified expression that's equal to the total distance is x^2+5x
