The standard form of the function in exercise 6 is:
f(x)=3x^2+18x+15
Complete the square to write the equation in
the standard form f (x) = a(x − h)^2 + k .

Answer 1

I got 3(x+3)^=66

Answer 2

How did you get that? Where did the f(x) go?

Answer 3

f(x)=3(x+3)^2=66

Answer 4

There shouldn't be an equals in the middle of your equation.
