Chapter 3 - Polynomial and Rational Functions - Concept and Vocabulary Check: 2

Answer

$(-∞, -5), (-5, -3), (-3, ∞)$

Work Step by Step

Since the inequality polynomial in Exercise 1 is $x^2 + 8x + 15 \gt 0$, the values of $x$ are not $inclusive$. Therefore, the intervals created are: $$(-∞, -5), (-5, -3), (-3, ∞)$$, excluding values $-5$ and $-3$.
