Answer 1

Answer:

B and E

Step-by-step explanation:

Answer 2

Answer: Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

$-3(y-y)^2-9+7y$

Simplification needs a few steps:

$-3(y-5)^2-9+7y\\=-3(y^2+25-10y)-9+7y\\=-3y^2-75+30y-9+7y\\=-3y^2+37y-84$

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.
