I'm guessing that the problem first asked to simplify
6z+%2B+1+%2B+4x%5E2+-+3y%5E3+%2B+7x+-+8y%5E2+%2B+2x%5E2+-+x+%2B+5z+-17
6z%2B1%2B4x%5E2-3y%5E3%2B7x+-8y%5E2+%2B2x%5E2-x+%2B5z+-17 = %286z%2B5z%29%2B%281-17%29%2B%284x%5E2%2B2x%5E2%29-3y%5E3%2B%28%2B7x-x%29-8y%5E2 = %286%2B5%29z%2B%28-16%29%2B%284%2B2%29x%5E2-3y%5E3%2B%287-1%29x-8y%5E2 = 11z-16%2B6x%5E2-3y%5E3%2B6x-8y%5E2
Maybe it would look better writing the terms in a more conventional order as
6x%5E2%2B6x-3y%5E3-8y%5E2%2B11z-16
The variables are x, y, and z .
The coefficients is the numbers 6, 6, -3, -8, and 11, that are multiplying the powers of the variables.
The number -16 can be called the constant, or the independent term.
