Question

Given that f(x)=x^2+11x+18 and g(x)=x+2, find f(x)-g(x) and express the result in standard form.

Answer 1

so the initial equations are:

`\begin{gathered} f(x)=x^2+11x+18 \\ g(x)=x+2 \end{gathered}`

the we can substract theme like:

`\begin{gathered} f(x)-g(x)=x^2+11x+18-(x+2) \\ f(x)-g(x)=x^2+11x+18-x-2 \end{gathered}`

and finally we can simplify it so:

`f(x)-g(x)=x^2-10x+16`
