Answer 1

For this case we have the following factorized expression:

$(2y-9) (2y-9)$

Applying distributive property we have:

$(2y) (2y) - (2y) (9) - (9) (2y) + (9) (9) =\\4y ^ 2-18y-18y + 81 =$

We add similar terms taking into account that: Equal signs are added and the same sign is placed.

$4y ^ 2-36y + 81$

ANswer:

$4y ^ 2-36y + 81$
