A positive minus a negative is a positive.
The quotient of a positive integer by a negative is always negative. Say this to yourself a couple times: "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
42n2 is divisible by 14n. (42n2 ÷ 14n = 3n.) Since the largest possible factor of 14n is itself, the greatest common factor is 14n.
The gcf of 14n and 42n^2 is 14n.

A negative minus a positive is a negative. i.e -1-(+1)= -2
