Answer

$13$ and $4$

Work Step by Step

The given function is $\Rightarrow y=x^2-17x+52$ Substitute $0$ for $y$. $\Rightarrow 0=x^2-17x+52$ Factor the trinomial. $\Rightarrow 0=(x-13)(x-4)$ Use zero product property. $\Rightarrow x-13=0$ or $x-4=0$ Solve for $x$. $\Rightarrow x=13$ or $x=4$ Hence, the zeros of the function are $13$ and $4$.
