Question

Let f(x) = -3x - 6 and g(x) = 5x + 2. Find f(x) + g(x).

Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow f(x) + g(x) = (f + g)(x) }\)

\(\Large \color{MidnightBlue}{\Rightarrow (-3x - 6) + (5x + 2) }\)

\(\Large \color{MidnightBlue}{\Rightarrow -3x - 6 + 5x + 2 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 2x - 4 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 2(x - 2) }\)
