Answer 16

okay I'll do it :P I know...I'm still gonna do it

Answer 17

\(f(x)= 2(x- 7)^2+15\)
(x-7)(x-7)
\(x^2-7x-7x+49\)
2\((x^2-14x+49\))
\(2x^2-28x+98\)
\(2x^2-28x+98+15\)
\(2x^2-28x+113\)

Answer 18

The last one is the answer.......
\(2x^2-28x+113\)
so this is in standard form.....I had done foil for the \((x-7)^2\) to get the \(x^2-14x+49\) then multiplied that all be 2, then added 15 to 98.....
