Answer 2

Answer:

Rewrite y4y4 as (y2)2(y2)2.

(y2)2−9(y2)2-9

Rewrite 99 as 3232.

(y2)2−32(y2)2-32

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)a2-b2=(a+b)(a-b) where a=y2a=y2 and b=3b=3.

(y2+3)(y2−3)(y2+3)(y2-3)

y4−9y4-9

9y9y

9y29y2

9y39y3
