Answer:

Hello,

Explanation:

do I remind you of the formula (a+b)²=a²+2ab+b²


f(x)=-(x+2)^2+3\\\\=-(x^2+4x+4)+3\\\\=-x^2-4x-4+3\\=-x^2-4x-1

Sorry i haven't see the sign minus before the parenthesis.

Answer:

F(x)=-x^2-4x-1

Explanation:

According to PEMDAS, do the exponent part for the parentheses, sense it goes first.

F(x)= -(x^2+4x+4)+3

Then distribute the - sign

F(x)= -x^2-4x-4+3

Then you simplify

F(x)= -x^2-4x-1
