Answer

$x^2 + 8x + 15 = 0$ boundary points

Work Step by Step

Polynomial inequalities are solved by setting the function $f(x)=0$. Thus, the equation $x^2 + 8x + 15 = 0$ must first be solved. The real solutions of this equation, $-5$ and $-3$, shown on the number line, are called boundary points.
