f(x) = (x + 2)2 and g(x) = x2 − (x + 2)2. Find f(x)-g(x)

Answer 1

2x2 + 8x + 8



3x2 + 8x + 8



x2 + 8x + 8



4x + 4



x2 − 8x + 8

Answer 2

\(\normalsize\color{blue}{ f(x) = (x + 2)^2}\)
\(\normalsize\color{blue}{ g(x) = x^2 − (x + 2)^2}\)

\(\normalsize\color{blue}{ f(x)~~-~~g(x)~ =(x + 2)^2~~-~( x^2 − (x + 2)^2~~)}\)

Answer 3

(x+2)² - [ x² - (x+2)² ]
(x+2)² - x² + (x+2)²
2(x+2)² - x²
2(x²+4x+4) - x²
2x²+8x+8 - x²
x²+8x+8

Answer 4

A parabola,

x²+8x+8
x²+8x+16 - 8
(x+4)² - 8

Answer 5

Well, you just need the `x²+8x+8`
