Quick question.
Started first semester of engineering. First week homework problems just a basic recap of high school, ie- basic functions,trig, algebra.
All questions are straightforward except the last 6 which ask to "complete the squares". Im aware of how to do this but each problem has only two terms and are written as an expression.
eg:
x^2+2x
or
36x^2-24x
Is it possible to "complete the squares" on these terms? Is this a mistype? Am I retarded?
thanks.

They mean:
>What term should you add so that you get the square of a linear function?
Your first example:
x^2 + 2x + ... = (x + ...)^2
In this case the solution is
x^2 + 2x + 1 = (x + 1)^2
For your other example:
36x^2 - 24x + ... = (6x + ...)^2
The solution is
36x^2 - 24x + 4 = (6x - 2)^2
They probably want you to solve these by trial and error for now.

Ahh i see. Thank you!
