Assume you meant 2y/(y + 4) - 2y/(y - 4) = (y^2 + 16)/(y^2 - 16) y^2 - 16, a difference of 2 squares, factors into (y + 4)(y - 4), which is a common denominator for all the fractions in the equation. On your second line you appeared to have multiplied the left side by this common denominator, but you neglected to show you multiplied the right side also. My second line is 2y(y - 4) - 2y(y + 4) = y^2 + 16 From there 2y^2 - 8y - 2y^2 - 8y) = y^2 + 16 -16y = y^2 + 16 0 = y^2 + 16y + 16 or y^2 + 16y + 16 = 0 Are you supposed to solve this quadratic equation, or just simplify it?
