All of these make use of the expansion
   (a + b)² = a² + 2ab + b²
You would do well to memorize this "formula." Of course, it also helps to be able to double (or halve) a number, and to know the squares of small integers.

1.
   x² +2x +1
   x² -6x +9
   x² +12x +36
   x² -0.4x +0.04
   4x² +28x +49
   9x² +30x +25

2.
   (x + 4)²
   (x + 3)²
   (x - 9)²
   (x - 5)²

3. (12/2)² = 36

4. ±2√49 = ±14
