Steps in getting the square of trinomial:
1. Square the first term.
2. Square the second term.
3. Square the last term.
4. Multiply the first and second term, then, square them.
5. Multiply the second and third term, then, square them.
6. Lastly, multiply the first and last term, then, square them.
Examples:
(a+b+c)^2
1st step: a^2
2nd step: b^2
3rd step: c^2
4th step: ab^2
5th step: bc^2
6th step: ac^2
Then the answer will be, a^2+b^2+c^2+ab^2+bc^2+ac^2.
