Consider the expression –3(y – 5)2 – 9 + 7y.

Which statements are true about the process and simplified product? Check all that apply.


A=The first step in simplifying is to distribute the –3 throughout the parentheses.

B=There are 3 terms in the simplified product.

C=The simplified product is a degree 3 polynomial.

D=The final simplified product is –3y2 + 7y – 9.

E=The final simplified product is –3y2 + 37y – 84.

Verified Answer :

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.

Answer:

B and E
