Inventory Variance Analysis: Identifying X-Intercepts

An inventory manager uses the quadratic model y=x2+2x8y = x^2 + 2x - 8 to represent the variance in stock levels over an eight-hour shift. In this model, the x-intercepts represent the specific times when the variance is exactly zero. Based on the algebraic solution for this specific equation, list the coordinates of these two x-intercepts.
