anonymous · Answer

first one 
$$x^2-25=0$$
$$x^2=25$$
$$x=\pm\sqrt{25}=\pm5$$

anonymous · Answer

which really means $x=-5$ or $x=5$

anonymous · Answer

second one 
$$ x^2 = 2x + 15$$
$$x^2-2x-15=0$$ then factor

anonymous · Answer

Part 2: Describe what the solution(s) represent to the graph of each. 
the zeros are where the graph of $y=x^2-25$ cross the $x$ axis
same for $y=x^2-2x-15$
