Multiple Choice

A resource analyst is calculating the break-even points for a project using the quadratic model y=x2−4x−5y = x^2 - 4x - 5. After factoring the equation into 0=(x−5)(x+1)0 = (x - 5)(x + 1), which mathematical property allows the analyst to find the solutions x=5x=5 and x=−1x=-1 by setting each individual factor to zero?
