Question

Simplify: –3(y + 2)2 – 5 + 6y What is the simplified product in standard form?

Answer 1

Answer:

-3(y²+4y+4)-5+6y

multiply/distribute

-3y²-12y-12-5+6y

regroup like terms

-3y²-12y+6y-12-5

-3y²-6y-17

that is standard  form

Step-by-step explanation:

Answer 2

Standard form, I assume is ay^2+by+c
so expand this stuff
-3(y+2)^2-5+6y
do exponent first
(y+2)^2=(y+2)(y+2)=y²+2y+2y+4=y²+4y+4
now

-3(y²+4y+4)-5+6y
multiply/distribute
-3y²-12y-12-5+6y
regroup like terms
-3y²-12y+6y-12-5
-3y²-6y-17
that is standard  form
