Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

☆Given=>Equation=y^2-9

=>y^2-9

=>(y)^2-(3)^2

=>(y+3)(y-3) [As a^2-b^2=(a+b)(a-b)].

☞So from here, the factors are (y+3) and (y-3) and the zeroes are y=3 and y=-3.
