A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the general form of the perpendicular bisector equation of the line segment of z 2z and 3z 8z?

Mid-point: (3z+z)/2, (2z+8z)/2 = (2z, 5z) Slope: (8z-2z)/(3z-z) = 6z/2z = 3 Perpendicular slope: -1/3 Equation: y -5z = -1/3(x -2z) => y = -1/3x+2z/3+5z => y = -1/3x+17z/3 General form of the bisector equation: x+3y-17z = 0

2x - 2y plus 5z - 2x - y plus 3z simplify?

well, this is pretty easy, just look at it logically:2x - 2y + 5z - 2x - y + 3zwhen you are trying to simplify a formula, your best practice would be to always begin with "organizing" the numbers, in this case it would become:2x - 2x -2y - y + 5z +3zwhen you organize it, it becomes clear what you need to do; first you get rid of the "opposing" values which cancel each other out, in this case the 2x:2x - 2x -2y - y + 5z +3z = -2y - y + 5z + 3zWhen two numbers have the exact same values but one is positive and the other is negative, their result is always zero, so you can simply erase them. In the opposite, when both of them are positive or both of them are negative, then they add up to each other:-2y - y + 5z +3z = -3y + 8z OR 8z - 3yFor this one, I don't think it can be simplified further, 8z - 3y is its' simplest form.
