Solve for \( y \). \[ y^{2}-y-2=0 \] If there is more than one solution, separate them with commas. If there is no solution, click on "No solution." \( y=\square \)

1. Start with the quadratic equation: \[ y^2 - y - 2 = 0 \] 2. Factor the quadratic by finding two numbers that multiply to \(-2\) and add to \(-1\). The numbers \(-2\) and \(1\) satisfy these conditions: \[ y^2 - y - 2 = (y - 2)(y + 1) \] 3. Set each factor equal to zero and solve for \( y \): \[ y - 2 = 0 \quad \text{or} \quad y + 1 = 0 \] \[ y = 2 \quad \text{or} \quad y = -1 \] 4. The solutions are: \[ y = 2, -1 \]
