Answer

$-8$ and $3$

Work Step by Step

The given function is $\Rightarrow g(x)=x^2+5x-24$ Substitute $0$ for $g(x)$. $\Rightarrow 0=x^2+5x-24$ Factor the trinomial. $\Rightarrow 0=(x+8)(x-3)$ Use zero product property. $\Rightarrow x+8=0$ or $x-3=0$ Solve for $x$. $\Rightarrow x=-8$ or $x=3$ Hence, the zeros of the function are $-8$ and $3$.
