How do I find the additive inverse of 2X^2 -3X -1?
For y to be the additive inverse of 2x? - 3x -1 it must satisfy the equation: (2x? - 3x -1) + y 0 Solving for y we obtain 2x? - 3x -1 - y -(2x? - 3x -1) y -2x? + 3x + 1 y Is the correct answer.
A good shake will remove most then use a lint roller to finish off.
With a lint roller! duhhh :)
