Quizplus · Accepted Answer

To find the values of $x$ for which $f(x) = 0$, we solve the equation $x^2 - 15x + 56 = 0$. Factoring the quadratic equation, we get $(x - 7)(x - 8) = 0$, which gives $x = 7$ and $x = 8$. To find $f(0)$, we substitute $x = 0$ into the function: $f(0) = 0^2 - 15(0) + 56 = 56$.
